request.GetResponse gives always a Timeout
Solution 1
So does it hang on req.GetRequestStream()
every time, or does it work "a few tries" and then hang?
If it works a few times and then hangs, it's possible that you're not closing the requests properly, which is causing you to run out of connections. Make sure to Close()
and/or Dispose()
the HttpWebResponse
objects and all of the Streams and Readers that you're creating.
Solution 2
You have to use response.Dispose();
end of the method

I made a Function for a program, which does work when the Request Type is
GET
, if it isPOST
, it always produces a Timeout Exception(and the timeout of 50s wasnt reached) on the LineHttpWebResponse response = (HttpWebResponse)request.GetResponse();
I tried many things, but I doesnt found out why, may someone here know it.
Edit: Got it to work, if someone is interested: https://gist.github.com/4347248
Any help will be greatly appreciated.
My Code is:public ResRequest request(string URL, RequestType typ, CookieCollection cookies, string postdata ="", int timeout= 50000) { byte[] data; Stream req; Stream resp; HttpWebRequest request = WebRequest.Create(URL) as HttpWebRequest; request.Timeout = timeout; request.ContinueTimeout = timeout; request.ReadWriteTimeout = timeout; request.Proxy = new WebProxy("127.0.0.1", 8118); request.Headers.Add(HttpRequestHeader.AcceptLanguage, "de"); request.Headers.Add("UA-CPU", "x86"); request.Headers.Add(HttpRequestHeader.AcceptEncoding, "gzip, deflate"); request.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; WOW64; SLCC1; .NET CLR 2.0.50727; Media Center PC 5.0; .NET CLR 3.5.21022; .NET CLR 3.5.30729; .NET CLR 3.0.30618) "; request.CookieContainer = new CookieContainer(); request.CookieContainer.Add(cookies); if (typ == RequestType.POST) { data = System.Text.Encoding.Default.GetBytes(postdata); request.Method = "POST"; request.ContentType = "application/x-www-form-urlencoded"; request.ContentLength = data.Length; req = request.GetRequestStream();//after a few tries this produced a Timeout error req.Write(data, 0, data.Length); req.Close(); HttpWebResponse response = (HttpWebResponse)request.GetResponse();//This line produces a Timeout Exception resp = response.GetResponseStream(); if ((response.ContentEncoding.ToLower().Contains("gzip"))) { resp = new System.IO.Compression.GZipStream(resp, System.IO.Compression.CompressionMode.Decompress); } else if ((response.ContentEncoding.ToLower().Contains("deflate"))) { resp = new System.IO.Compression.DeflateStream(resp, System.IO.Compression.CompressionMode.Decompress); } return new ResRequest() { result = new System.IO.StreamReader(resp, System.Text.Encoding.UTF8).ReadToEnd(), cookies = response.Cookies, cstring = cookiestring(response.Cookies) }; } else { request.Method = "GET"; HttpWebResponse response = (HttpWebResponse)request.GetResponse(); resp = response.GetResponseStream(); if ((response.ContentEncoding.ToLower().Contains("gzip"))) { resp = new System.IO.Compression.GZipStream(resp, System.IO.Compression.CompressionMode.Decompress); } else if ((response.ContentEncoding.ToLower().Contains("deflate"))) { resp = new System.IO.Compression.DeflateStream(resp, System.IO.Compression.CompressionMode.Decompress); } return new ResRequest() { result = new System.IO.StreamReader(resp, System.Text.Encoding.UTF8).ReadToEnd(), cookies = response.Cookies, cstring = cookiestring(response.Cookies) }; } }
