Consecutive Http posts..

[baron06]

Hi all ;

I'm posting a html form with the code below

            req = (HttpWebRequest)WebRequest.Create("http://www.domain.com/login.php?");
            req.AllowAutoRedirect = true;
            req.Method = "POST";
            req.ContentType = "application/x-www-form-urlencoded";
            byte[] bytes = Encoding.ASCII.GetBytes(parameters.ToString());
            req.ContentLength = bytes.Length;
            Stream writer = req.GetRequestStream();
            writer.Write(bytes, 0, bytes.Length);
            writer.Close();
            HttpWebResponse response = (HttpWebResponse)req.GetResponse();
 

But when I try to post the form with 3 or greater different user names(i.e when I write the above code 3 times or greater , or in a loop which enumerates 3 times or greater) a web exception("The operation has timed out") occurs in the 3 rd occurance of "writer = req.GetRequestStream();"

I've tried to increase the timeout but I didn't achieve and I've searched a lot of web sites about this issue but I couldn't find any solution...

Have you got any troubleshooting tips ???

Thanks...
