Calling web services from behind a proxy server

Calling web services from behind a proxy server

When you use a web service’s proxy class, the calls to the web service might fail if you’re behind a proxy server. To solve the problem, you set the Proxy property of a web service’s proxy class to an instance of WebProxy, that contains the HTTP proxy settings needed for the web method calls. Here’s an example:

Dim myService As New MyWebServiceDim proxyObject As New System.Net.WebProxy("http://proxyserver:80/", True)myService.Proxy = proxyObjectmyService.MyMethod()

The same issue, and this solution, applies also to the WebRequest class, that you typically use to download the HTML source code at the specified URL, as shown in this routine.
