WebApache HttpClient PUT HTTP Request Example Apache HttpClient DELETE HTTP Request Example If you want to dig deeper and learn other cool things you can do with . WebDec 12,  · HttpClient Downloads. The latest release available for download: Release packages – Release Notes – License. Dependency management. If you are using a . WebMay 26,  · Let’s do a small Demo for the example of uploading and downloading files initiated by the local client. HttpClient has two forms, 1 kind is org. apache. http, 1 kind . WebStep 1 – Download the dependency JAR file Open the official homepage of the HttpClient (components) website and go to the download page Then, download the latest stable .

This is the foundation for data communication for the World Wide Web i. HTTP is a eownload and stateless examplw which can be used for other purposes as well using extensions of its request methods, error codes, and headers. The default port is TCP 80, but other ports can be used as well.

It provides a standardized way for computers to communicate with each other. HTTP specification defines how clients’ request apache httpclient download file example will be constructed and sent to httpclent server, and how the servers respond to these requests. Http client is a transfer library, it resides on the httpcliebt side, sends and receives HTTP messages.

It provides up to date, feature-rich and, efficient implementation which meets the recent HTTP standards. In addition to this using client library, one can apache httpclient download file example HTTP based applications such as web browsers, web service clients, etc.

HttpClient down,oad supports sending requests through multiple threads. It manages multiple connections established from various threads using ClientConnectionPoolManager. Before proceeding with the installation, make sure that you already have Eclipse installed замечательная openproj download free windows полезно!!! your system.

If not, download and install Eclipse. For more information on Eclipse, please refer to our Eclipse Tutorial. Open apache httpclient download file example htptclient homepage of the HttpClient components website and go to the download page.

Then, download the latest stable version of HttpClient. Here, apace the tutorial, we are using the version 4. Within the downloaded folder, you will find a folder named lib and this contains the required Jar files that are to be added in the classpath of your project, exanple work with HttpClient.

Open eclipse http://replace.me/18038.txt create a sample project. Apcahe using GET should only retrieve data and should have no other effect on the data.

The constructor of this class accepts a String value representing the URI. Exampple POST request is used to send data to the server; for example, customer information, file upload, etc. The createDefault method of the HttpClients apxche returns an object of the class CloseableHttpClientwhich is the base implementation of the HttpClient interface. This sends required data and retrieves the information of the given server using a URI.

Create this request by instantiating the HttpPost apache httpclient download file example and pass a string value representing the URI, as a parameter to its constructor. Processing the HTTP responses using the response handlers is recommended. In this chapter, we are going to discuss how to create response handlers and how to use them to process a response.

In order to create a response handler, implement this interface and override apache httpclient download file example handleResponse method.

Every response has a status code and if the status code is in between andthat a;ache the action was successfully received, understood, and accepted. Therefore, in our example, we will handle the entities of the responses with such status codes. Using apacje method create an HttpClient object. Create an HttpGet request by instantiating the HttpGet class and by passing перейти на источник string representing the URI as a parameter to its constructor.

The CloseableHttpClient class has a variant of execute method httpdlient accepts two objects ResponseHandler and HttpUriRequest, and returns a response object. If you are processing HTTP responses manually instead of using a response handler, you need to close all the http connections by yourself. This chapter explains how to close the connections manually.

Start a try-finally block, write the remaining code in the programs in the try block and close the CloseableHttpClient object in the finally block. Start another try-finally apacje nested within the перейти try-finallywrite the remaining code in the programs in this try block and close the HttpResponse object in the finally httpcclient.

You can abort the current HTTP request using the abort method, i. Читать this method is invoked after one execution, responses of that execution will not be affected and the subsequent executions will be aborted. If you observe the following example, we have created a HttpGet request, printed the request format used using the getMethod. Then, we have carried out another execution with the same request. Printed the status line using the 1 st execution again.

Finally, printed the status line of the second execution. As discussed, the responses of the 1 st execution execution before abort method are printed including the second status line that is written after the abort method and, all the subsequent executions of the current request after the abort method are failed invoking an exception. Interceptors are those which helps to apache httpclient download file example or change requests or responses.

Protocol interceptors in general act upon a specific header or a group apsche related headers. HttpClient library provides support for interceptors. The HttpRequestInterceptor interface represents the request interceptors. This interface contains a method known as a process in which you need to write the chunk of code to intercept the requests.

Create an object of the HttpRequestInterceptor interface by implementing its abstract method process. Following example demonstrates the usage of request interceptors. In apache httpclient download file example processor method of the interceptor, we are verifying the headers of the request sent; if any of those headers is sample-headerwe are trying to remove it and display the list of headers of that particular request.

The HttpResponseInterceptor apache httpclient download file example represents the response interceptors. This interface contains a method known as process. In this method, you exxmple to write the chunk of code to intercept the responses. Create an object apache httpclient download file example the HttpResponseInterceptor interface by implementing its abstract method process. The following example demonstrates the usage of response interceptors.

In htypclient example, we have added three headers: sample-header, demo-header, and test-header to the response in the processor. After executing the downlad and obtaining the response, we printed names of all the headers of the приведенная ссылка using the getAllHeaders method. Using HttpClient, you can connect to a website which needed username and password.

This chapter explains, how to execute a client request against a site that asks for username and password.

The CredentialsProvider Interface maintains a collection to hold the user login credentials. You can httpclidnt its nfs underground download full version free pc by instantiating the BasicCredentialsProvider class, the default implementation of this interface.

You can set the required credentials to the CredentialsProvider object using the setCredentials method. Set the CredentialProvider htpclient created in the previous step to the client builder by passing it to the CredentialsProvider object method as shown below. Create a HttpRequest object by instantiating the HttpGet class.

Execute this request using the execute method. Following is apache httpclient download file example example program which demonstrates the execution of a HTTP request against a target site that requires user authentication.

A Proxy server is an intermediary server between the client and the internet. Instantiate the Apache httpclient download file example class of the org. In download left 4 dead pc kickass same way, create another Apache httpclient download file example object to привожу ссылку the target host to which requests need to be straszne gry pc. The HttpRoutePlanner interface computes a route to a specified host.

Create an object of this interface by instantiating the DefaultProxyRoutePlanner class, an implementation of this interface. Using the custom method of the HttpClients class, create a HttpClientBuilder object and, to this object set the route planner created above, using the setRoutePlanner method.

One of the variants of the execute method accepts exanple HttpHost and HttpRequest objects and executes the request. Following example demonstrates how to send a HTTP request to a server via proxy. We have printed the headers of the response and the body of the httlclient. In this chapter, we will learn how to create a HttpRequest authenticated httpclienh username and password and tunnel it through a proxy to a target host, using an example. Set the credentials using the setCredentials method for both host and proxy as shown below.

Pass the previously created CredentialsProvider object to this method. Create a RequestConfig. Builder object using the custom method. Set жмите сюда previously created proxyHost object to the RequestConfig.

Builder using the setProxy method. Finally, build the RequestConfig apache httpclient download file example using the build method. Create a HttpGet object by instantiating the HttpGet class. Set the config object created in the previous step to this object using the setConfig method. Execute the request by passing the HttpHost object target and request HttpGet as parameters to the execute method. Following example demonstrates how to execute a Apache httpclient download file example request through a proxy using username apache httpclient download file example password.

The class RequestBuilder is used to build request by adding parameters tile it. After setting the required parameters, build the Examp,e object using the build method. Execute the HttpUriRequest created in the apahe steps by passing it to the execute method. Following apache httpclient download file example demonstrates how to logon to a form by sending login credentials.

You can print the contents of the CookieStore object where you can see your parameters along with the previous ones the page stored in case. To print the apache httpclient download file example, get all the cookies from the CookieStore object using the getCookies htttpclient. This method returns a List object. Cookies are text files stored on the client computer and they are kept for various information tracking purpose.

The CookieStore interface represents the abstract store for Cookie objects. You can create a cookie store by instantiating the Httpcliebt class, a default implementation of apache httpclient download file example interface. In addition to the functionalities of a cookie, ClientCookie can get the original cookies in the server.

Set the previously created proxyHost object to the RequestConfig. Builder using the setProxy method. Finally, build the RequestConfig object using the build method. Create a HttpGet object by instantiating the HttpGet class. Set the config object created in the previous step to this object using the setConfig method.

Execute the request by passing the HttpHost object target and request HttpGet as parameters to the execute method. Following example demonstrates how to execute a HTTP request through a proxy using username and password. The class RequestBuilder is used to build request by adding parameters to it. After setting the required parameters, build the HttpUriRequest object using the build method. Execute the HttpUriRequest created in the previous steps by passing it to the execute method.

Following example demonstrates how to logon to a form by sending login credentials. You can print the contents of the CookieStore object where you can see your parameters along with the previous ones the page stored in case. To print the cookies, get all the cookies from the CookieStore object using the getCookies method.

This method returns a List object. Cookies are text files stored on the client computer and they are kept for various information tracking purpose.

The CookieStore interface represents the abstract store for Cookie objects. You can create a cookie store by instantiating the BasicCookieStore class, a default implementation of this interface.

In addition to the functionalities of a cookie, ClientCookie can get the original cookies in the server. You can create a client cookie by instantiating the BasicClientCookie class. To the constructor of this class, you need to pass the key-value pair that you desired to store in that particular cookie. You can add cookies to the cookie store using the addCookie method of the BasicCookieStore class.

Following example demonstrates how to create cookies and add them to a cookie store. Here, we created a cookie store, a bunch of cookies by setting the domain and path values, and added these to the cookie store.

You can get the cookies added to a cookie store using getCookies method of the asicCookieStore class. This method returns a list which holds all the cookies in the cookie store. Following example demonstrates how to retrieve cookies from a cookie store. Here, we are adding a bunch of cookies to a cookie store and retrieving them back. A multi-threaded program contains two or more parts that can run concurrently and each part can handle a different task at the same time making optimal use of the available resources.

If you want to execute multiple client requests from threads consecutively, you need to create a ClientConnectionPoolManager. It maintains a pool of HttpClientConnections and serves multiple requests from threads.

The connections manager pools the connections based on the route. If the manager has connections for a particular route, then it serves new requests in those routes by leasing an existing connection from the pool, instead of creating a new one.

Make sure that you have created a class, made it a thread either by extending the thread class or, by implementing the Runnable interface and implemented the run method. Following example demonstrates the execution of HTTP requests simultaneously from multiple threads. In this example, we are trying to execute various requests from various threads and trying to print the status, and the number of bytes read by each client.

Using Secure Socket Layer, you can establish a secured connection between the client and server. It helps to safeguard sensitive information such as credit card numbers, usernames, passwords, pins, etc. The HttpClient here is org apache. This way, similar to the above, only becomes FileBody. The Part array above corresponds to HttpEntity here. No matter which way the client uploads, the server handles it the same way. After obtaining the parameters through HttpServletRequest, the resulting Item is classified into ordinary forms and File forms.

After processing, the server can set the simple information returned to the client in Header. If the return client is a stream, the size of the stream must be set in advance! The most basic function of HttpClient is to implement the Http method. Only the file path is wrong.

Note: This sample is part of a продолжение здесь collection of UWP feature samples. You can download this sample as a standalone ZIP file from docs. For more samples, see the Samples portal on the Windows Dev Center. Each of these requests is sent as an asynchronous operation.

The HttpClient class can be used in scenarios that use text as well as scenarios that use arbitrary streams of data. Filters see Windows. Filters can be chained together in a sequence to address more complex web service issues. Scenario Use a filter to adapt download behavior based on whether the device is on a metered network connection or not.

Note This sample by default requires network access using the loopback interface. For a sample that shows how to use HttpClient so that the app is always connected and always reachable using background network notifications in a Universal Windows Platform UWP app, download the ControlChannelTrigger HttpClient sample.

This sample uses the Try versions of the HttpClient methods which do not raise exceptions. For a version that uses the exception-based methods, see the v7. This sample requires that network capabilities be set in the Package. These capabilities can be set in the app manifest using Microsoft Visual Studio. For more information on network capabilities, see How to set network capabilities. HttpClient Windows. Http Windows. Headers Windows. The next steps depend on whether you just want to deploy the sample or you want to both deploy and run it.

This sample requires that a web server is available for http://replace.me/18181.txt app to access for uploading and downloading files.

The web server must be started before the app is run. The web server must also have apache httpclient download file example HttpClientSample path available for uploads and downloads.

The easiest way to run the sample is to use the provided web server scripts. Browse to the Server folder in your sample folder to setup and start the web server. There are two options possible. Apache httpclient download file example the web server is not needed anymore, please browse to the Server folder in you sample folder and run one of the following:. The sample can run using other web servers or websites, not only the one provided with the apache httpclient download file example.

However for scenarios in the sample, the web server may need to be configured to interpret the query string and cookies similar to IIS so it can send the expected responses.

If IIS is used on a different computer, then the previous scripts can be used with minor changes. The sample must also be updated when run against a non-localhost web server. To apache httpclient download file example the sample for use with IIS on a different device:.

Instead, set up the web server on a separate bit or bit computer and follow the steps for using the sample against non-localhost web server. Note When used with the supplied scripts, this sample communicates with another process IIS server which is a desktop app on the same machine over loopback for demonstration purposes only. A UWP app that communicates apache httpclient download file example loopback to another process that represents a UWP app or a desktop app is not allowed and such apps will not pass Microsoft Store validation.

For more information, see How to enable loopback and troubleshoot network isolation. However if a server different than IIS is used, then this requires some special configuration of the server to create the HttpClientSample folder. The target URI field should be updated.

The HTTP protocol is probably the most used and important protocol on Internet today, and more and more Java applications need to access network resources directly through the HTTP protocol. While basic access to the HTTP protocol is already provided in the java. HttpClient is designed to provide an efficient, up-to-date, and feature-rich client programming toolkit that supports the HTTP protocol, and it supports the latest versions and recommendations of the HTTP protocol.

In most cases, we use Chrome or other browsers to access an WEB server, which can be used to browse the page, view information or submit some data, upload or download files, etc. Some of these pages are just plain old pages, some require users to log in before they can use them, or require authentication, and some are transmitted encrypted, such as HTTPS.

None of these situations are a problem with the browsers we currently use. But what if we need to access the server’s resources without a browser? So what to do? Let’s do a small Demo for the example of uploading and downloading files initiated by the local client. HttpClient has two forms, 1 kind is org. File uploads can be done in two ways: PostMethod and HttpPost. The treatment is much the same.

When passing a file stream to a server, other parameters can be passed at the same time. Wrap the file into FilePart and put it into the Part array. At the same time, other parameters can be put into StringPart.

The HttpClient here is org apache. This way, similar to the above, only becomes FileBody. The Part array above corresponds to HttpEntity here. No matter which way the client uploads, the server handles it the same way. After obtaining the parameters through HttpServletRequest, the resulting Item is classified into ordinary forms and File forms. After processing, the server can set the simple information returned to the client in Header.

If the return client is a stream, the size of the stream must be set in advance! The most basic function of HttpClient is to implement the Http method. The user only needs to provide the Http request object, and HttpClient will send the http request to the target server and receive the response from the server. If the http request is not executed successfully, httpclient will throw an exception.

So pay attention to finally when you’re writing code. All Http requests have one request column request line , including the method name, the requested URI and Http version Numbers. Home Java Use HttpClient to upload and download files. Through ServletFileUpload, you can set the size and encoding format of the uploaded file. In short, the server handles the resulting parameters as if they were HTML forms. For now, use org. HttpClient 1 more.

If the http request is not executed successfully, httpclient will throw an exception. So pay attention to finally when you’re writing code. All Http requests have one request column request line , including the method name, the requested URI and Http version Numbers.

Home Java Use HttpClient to upload and download files. Through ServletFileUpload, you can set the size and encoding format of the uploaded file. In short, the server handles the resulting parameters as if they were HTML forms.

Using the custom method of the HttpClients class, create a HttpClientBuilder object and, to this object set the route planner created above, using the setRoutePlanner method. One of the variants of the execute method accepts an HttpHost and HttpRequest objects and executes the request. Following example demonstrates how to send a HTTP request to a server via proxy.

We have printed the headers of the response and the body of the response. In this chapter, we will learn how to create a HttpRequest authenticated using username and password and tunnel it through a proxy to a target host, using an example. Set the credentials using the setCredentials method for both host and proxy as shown below. Pass the previously created CredentialsProvider object to this method. Create a RequestConfig. Builder object using the custom method.

Set the previously created proxyHost object to the RequestConfig. Builder using the setProxy method. Finally, build the RequestConfig object using the build method. Create a HttpGet object by instantiating the HttpGet class. Set the config object created in the previous step to this object using the setConfig method. Execute the request by passing the HttpHost object target and request HttpGet as parameters to the execute method.

Following example demonstrates how to execute a HTTP request through a proxy using username and password. The class RequestBuilder is used to build request by adding parameters to it. After setting the required parameters, build the HttpUriRequest object using the build method. Execute the HttpUriRequest created in the previous steps by passing it to the execute method. Following example demonstrates how to logon to a form by sending login credentials.

You can print the contents of the CookieStore object where you can see your parameters along with the previous ones the page stored in case. To print the cookies, get all the cookies from the CookieStore object using the getCookies method.

This method returns a List object. Cookies are text files stored on the client computer and they are kept for various information tracking purpose.

Following example demonstrates how to create cookies and add them to a cookie store. Here, we created a cookie store, a bunch of cookies by setting the domain and path values, and added these to the cookie store. You can get the cookies added to a cookie store using getCookies method of the asicCookieStore class.

This method returns a list which holds all the cookies in the cookie store. Following example demonstrates how to retrieve cookies from a cookie store.

Here, we are adding a bunch of cookies to a cookie store and retrieving them back. A multi-threaded program contains two or more parts that can run concurrently and each part can handle a different task at the same time making optimal use of the available resources. If you want to execute multiple client requests from threads consecutively, you need to create a ClientConnectionPoolManager. It maintains a pool of HttpClientConnections and serves multiple requests from threads.

The connections manager pools the connections based on the route. If the manager has connections for a particular route, then it serves new requests in those routes by leasing an existing connection from the pool, instead of creating a new one. Make sure that you have created a class, made it a thread either by extending the thread class or, by implementing the Runnable interface and implemented the run method.

Following example demonstrates the execution of HTTP requests simultaneously from multiple threads. In this example, we are trying to execute various requests from various threads and trying to print the status, and the number of bytes read by each client. Using Secure Socket Layer, you can establish a secured connection between the client and server.

It helps to safeguard sensitive information such as credit card numbers, usernames, passwords, pins, etc. Create its object using the custom method of the SSLContexts class. Save this as your key store file with extension. Load the keystore file and, its password which is changeit by default using the loadTrustMaterial method of the SSLContextBuilder class.

Около часа, говоришь? – хмуро спросил.  – А что ты скажешь о проверках пределов памяти, которые мы выполняли. Сьюзан пожала плечами. – Ну, если вы имеете в виду и диагностику, то времени уходило .

Кто дал вам наш номер. Уверен, наш постоянный клиент. Мы можем обслужить вас по особому тарифу. – Ну… вообще-то никто не давал мне ваш номер специально.

You can create its object by instantiating the BasicCredentialsProvider class, the default implementation of this interface. You can set the required credentials to the CredentialsProvider object using the setCredentials method.

Set the CredentialProvider object created in the previous step to the client builder by passing it to the CredentialsProvider object method as shown below. Create a HttpRequest object by instantiating the HttpGet class. Execute this request using the execute method. Following is an example program which demonstrates the execution of a HTTP request against a target site that requires user authentication.

A Proxy server is an intermediary server between the client and the internet. Instantiate the HttpHost class of the org. In the same way, create another HttpHost object to represent the target host to which requests need to be sent. The HttpRoutePlanner interface computes a route to a specified host. Create an object of this interface by instantiating the DefaultProxyRoutePlanner class, an implementation of this interface.

Using the custom method of the HttpClients class, create a HttpClientBuilder object and, to this object set the route planner created above, using the setRoutePlanner method. One of the variants of the execute method accepts an HttpHost and HttpRequest objects and executes the request. Following example demonstrates how to send a HTTP request to a server via proxy. We have printed the headers of the response and the body of the response. In this chapter, we will learn how to create a HttpRequest authenticated using username and password and tunnel it through a proxy to a target host, using an example.

Set the credentials using the setCredentials method for both host and proxy as shown below. Pass the previously created CredentialsProvider object to this method. Create a RequestConfig. Builder object using the custom method. Set the previously created proxyHost object to the RequestConfig. Builder using the setProxy method.

Finally, build the RequestConfig object using the build method. Create a HttpGet object by instantiating the HttpGet class. Set the config object created in the previous step to this object using the setConfig method. Execute the request by passing the HttpHost object target and request HttpGet as parameters to the execute method. Following example demonstrates how to execute a HTTP request through a proxy using username and password.

The class RequestBuilder is used to build request by adding parameters to it. After setting the required parameters, build the HttpUriRequest object using the build method. Execute the HttpUriRequest created in the previous steps by passing it to the execute method.

Following example demonstrates how to logon to a form by sending login credentials. You can print the contents of the CookieStore object where you can see your parameters along with the previous ones the page stored in case. To print the cookies, get all the cookies from the CookieStore object using the getCookies method. This method returns a List object. Cookies are text files stored on the client computer and they are kept for various information tracking purpose.

The CookieStore interface represents the abstract store for Cookie objects. You can create a cookie store by instantiating the BasicCookieStore class, a default implementation of this interface. In addition to the functionalities of a cookie, ClientCookie can get the original cookies in the server. You can create a client cookie by instantiating the BasicClientCookie class.

To the constructor of this class, you need to pass the key-value pair that you desired to store in that particular cookie. You can add cookies to the cookie store using the addCookie method of the BasicCookieStore class. Following example demonstrates how to create cookies and add them to a cookie store. Here, we created a cookie store, a bunch of cookies by setting the domain and path values, and added these to the cookie store.

You can get the cookies added to a cookie store using getCookies method of the asicCookieStore class. This method returns a list which holds all the cookies in the cookie store. Following example demonstrates how to retrieve cookies from a cookie store. Here, we are adding a bunch of cookies to a cookie store and retrieving them back.

A multi-threaded program contains two or more parts that can run concurrently and each part can handle a different task at the same time making optimal use of the available resources.

If you want to execute multiple client requests from threads consecutively, you need to create a ClientConnectionPoolManager. It maintains a pool of HttpClientConnections and serves multiple requests from threads. The connections manager pools the connections based on the route.

If the manager has connections for a particular route, then it serves new requests in those routes by leasing an existing connection from the pool, instead of creating a new one. Make sure that you have created a class, made it a thread either by extending the thread class or, by implementing the Runnable interface and implemented the run method. Following example demonstrates the execution of HTTP requests simultaneously from multiple threads.

In this example, we are trying to execute various requests from various threads and trying to print the status, and the number of bytes read by each client. Using Secure Socket Layer, you can establish a secured connection between the client and server.

It helps to safeguard sensitive information such as credit card numbers, usernames, passwords, pins, etc. Create its object using the custom method of the SSLContexts class. Save this as your key store file with extension. Load the keystore file and, its password which is changeit by default using the loadTrustMaterial method of the SSLContextBuilder class. An SSLContext object represents a secure socket protocol implementation.

Build an SSLContext using the build method. Using this, you can verify the Https server using a list of trusted certificates and authenticate the given Https server.

You can create this in many ways. Depending on the way you create an SSLConnectionSocketFactory object, you can allow all hosts, allow only self-signed certificates, allow only particular protocols, etc.

To allow only particular protocols , create SSLConnectionSocketFactory object by passing an SSLContext object, string array representing the protocols need to be supported, string array representing the cipher suits need to be supported and a HostnameVerifier object to its constructor. Using HttpClient, we can perform Multipart upload, i.

In this chapter, we demonstrate the multipart upload in HTTP client by uploading a simple text file. FileBody class represents the binary body part backed by a file. Instantiate this class by passing a File object and a ContentType object representing the type of the content. Create its object using the create method of the same class. Set it to the desired mode using the setMode method.

Using the methods addTextBody , addPart and, addBinaryBody , you can add simple text, files, streams, and other objects to a MultipartBuilder.

Add the desired contents using these methods. This sample uses the Try versions of the HttpClient methods which do not raise exceptions.

For a version that uses the exception-based methods, see the v7. This sample requires that network capabilities be set in the Package. These capabilities can be set in the app manifest using Microsoft Visual Studio. For more information on network capabilities, see How to set network capabilities. HttpClient Windows.

Http Windows. Headers Windows. The next steps depend on whether you just want to deploy the sample or you want to both deploy and run it. This sample requires that a web server is available for the app to access for uploading and downloading files. The web server must be started before the app is run. The web server must also have an HttpClientSample path available for uploads and downloads. The easiest way to run the sample is to use the provided web server scripts.

Browse to the Server folder in your sample folder to setup and start the web server. There are two options possible. When the web server is not needed anymore, please browse to the Server folder in you sample folder and run one of the following:.

The sample can run using other web servers or websites, not only the one provided with the sample. However for scenarios in the sample, the web server may need to be configured to interpret the query string and cookies similar to IIS so it can send the expected responses. If IIS is used on a different computer, then the previous scripts can be used with minor changes. The sample must also be updated when run against a non-localhost web server.

To configure the sample for use with IIS on a different device:. Instead, set up the web server on a separate bit or bit computer and follow the steps for using the sample against non-localhost web server.
