The performance of this call is very slow when it is called the first time
within a program. ( 5 - 6 seconds ) However the second time I call this
method is very fast. ( 10 - 40 ms ). It does not matter how long I wait
between subsequent calls it is still fast.

Specifics:

Windows XP x64 with retail version of .net FrameWork 2.0
Web Site is remote but is very responsive. if I call the URL directly from a
Web browser.
The call returns an XML string.

Any help will be appreciated... Code fragement is below.

HttpWebRequest HttpWReq =
(HttpWebRequest)WebRequest.Create("http://somewebsite.htm");
               Console.WriteLine("\r\nCall 1.");
               

               HttpWReq.Credentials = CredentialCache.DefaultCredentials;
               HttpWReq.MaximumAutomaticRedirections = 4;
               HttpWReq.MaximumResponseHeadersLength = 4;
               HttpWebResponse HttpWResp =
(HttpWebResponse)HttpWReq.GetResponse();
               Console.WriteLine("\r\nCall 2.");
