The base class for all XML Web service client proxies that use the HTTP transport protocol.
Assembly: System.Web.Services (in System.Web.Services.dll)
The properties on this class are used to control the behavior of the HTTP request object used to transmit the XML Web service request and response. The properties map to properties found on HttpWebRequest.
To communicate with an XML Web service using HTTP, you must create a proxy class deriving indirectly or directly from for the XML Web service. Instead of creating the proxy class manually, you can use the Wsdl.exe tool to create a proxy class for a given XML Web service's service description.
Since HttpWebClientProtocol is the base class for all proxy classes, its properties are on your proxy classes. These properties are useful for controlling the request behavior of the underlying transport. For example, use the Proxy property for calling XML Web services through a firewall. Many of these properties are used to initialize the HttpWebRequest that makes the Web request.
The following example is an ASP.NET Web Form, which calls an XML Web service named Math. Within the EnterBtn_Click function, the Web Form allows the server to automatically redirect the client to other sites. It also sets client authentication credentials, proxy settings, the request encoding and the time out for the request before calling the XML Web service method.
The properties on this class are copied into a new instance of a WebRequest object for each XML Web service method call. While you can call XML Web service methods on the same WebClientProtocol instance from different threads at the same time, there is no synchronization done to ensure that a consistent snapshot of the properties gets transferred to the WebRequest object. Therefore, if you need to modify the properties and make concurrent method calls from different threads you should use a different instance of the XML Web service proxy or provide your own synchronization.
