This is frequent question, but I tried everything and nothing helps.
HttpWebRequest hangs at line with GetResponse call. I already checked usings, connection limits and even disabled 100 Continue. I know there was bug with HttpWebRequest in .Net Framework 3.5, but version of my application pool is 4.0. Request from browser or constructed with Fiddler works as expected, page is accessible. What could it be else?
