Hello,
I have a HttpWebRequest POST function that does a HTTP POST, but after I do a post on a site it doesnt load the entire site. If I use same settings for HttpWebRequest just to load the site without doing a post, it loads just fine.
My code is,

byte[] buffer = Encoding.ASCII.GetBytes(post);
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(URL);
request.Timeout = 20000;
request.UserAgent = gettext(useragent);
request.ProtocolVersion = HttpVersion.Version10;
request.AllowAutoRedirect = true;
request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
request.ContentType = "application/x-www-form-urlencoded";
request.Referer = referer;
request.KeepAlive = true;
request.Method = "POST";
request.ContentLength = buffer.Length;
Stream PostData = request.GetRequestStream();
PostData.Write(buffer, 0, buffer.Length);
HttpWebResponse WebResp = (HttpWebResponse)request.GetResponse();
Stream Answer = WebResp.GetResponseStream();
StreamReader _Answer = new StreamReader(Answer);
_referer = WebResp.ResponseUri.ToString();
string vystup = _Answer.ReadToEnd();
html = RemoveBetween("<!--", "-->", vystup);
PostData.Close();
_Answer.Close();
Answer.Close();

Thanks in advance.

Looking over it quickly, it could be because you don't close the PostData stream until after you call request.GetResponse();

try this:

request.Method = "POST";
request.ContentLength = buffer.Length;
Stream PostData = request.GetRequestStream();
PostData.Write(buffer, 0, buffer.Length);

// moved this line of code here instead of at the end
PostData.Close();

HttpWebResponse WebResp = (HttpWebResponse)request.GetResponse();
Stream Answer = WebResp.GetResponseStream();
StreamReader _Answer = new StreamReader(Answer);
_referer = WebResp.ResponseUri.ToString();
string vystup = _Answer.ReadToEnd();
html = RemoveBetween("<!--", "-->", vystup);
_Answer.Close();
Answer.Close();
