httpwebrequest

i'm a getting forbidden (403) and Server Internal Error(500) when doing a request to a site even if when trying it with the browser, everything is fine. Here's my code and my appdata tag concerning httpwebrequest

HttpWebRequest request = (HttpWebRequest)WebRequest.Create( uri );

request.Method = "HEAD"; request.UserAgent = "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.2; Trident/4.0)"; request.AllowAutoRedirect = true; request.SendChunked = true; request.UnsafeAuthenticatedConnectionSharing = true; request.KeepAlive = false; request.Timeout = 7500; using( HttpWebResponse response = (HttpWebResponse)request.GetResponse() ) { request.Abort(); }

app settings:

Thank you!
