Status property contains a WebExceptionStatus value that indicates the source of the error. When WebException. Status is WebExceptionStatus. HttpWebRequest exposes common HTTP header values sent to the Internet resource as properties, set by methods, or set by the system; the following table contains a complete list. Note that servers and caches may change or add headers during the request.

The following table lists the HTTP headers that are set either by properties or methods or the system. HttpWebRequest is registered automatically. You do not need to call the RegisterPrefix method to register System. The local computer or application config file may specify that a default proxy be used. If the Proxy property is specified, then the proxy settings from the Proxy property override the local computer or application config file and the HttpWebRequest instance will use the proxy settings specified.

If no proxy is specified in a config file and the Proxy property is unspecified, the HttpWebRequest class uses the proxy settings inherited from Internet Explorer on the local computer. If there are no proxy settings in Internet Explorer, the request is sent directly to the server.

The HttpWebRequest class parses a proxy bypass list with wildcard characters inherited from Internet Explorer differently than the bypass list is parsed directly by Internet Explorer.

This differs from the native behavior of Internet Explorer. The Framework caches SSL sessions as they are created and attempts to reuse a cached session for a new request, if possible.

When attempting to reuse an SSL session, the Framework uses the first element of ClientCertificates if there is one , or tries to reuse an anonymous sessions if ClientCertificates is empty.

For security reasons, cookies are disabled by default. If you want to use cookies, use the CookieContainer property to enable cookies. NET Framework 4. This article explains how to modify your code so that the new behavior is disabled.

Gets or sets values indicating the level of authentication and impersonation used for this request. When overridden in a descendant class, gets or sets the name of the connection group for the request. When overridden in a descendant class, gets or sets the content length of the request data being sent.

Gets or sets the delegate method called when an HTTP continue response is received from the Internet resource. Gets or sets a timeout, in milliseconds, to wait until the Continue is received from the server.

The GetResponse method makes a synchronous request for the file specified in the RequestUri property and returns a FileWebResponse object that contains the response. When you want to write data to a file, the GetRequestStream method returns a Stream instance to write to. The FileWebRequest class relies on the File class for error handling and code access security.
