    copied!<p>I've been using the past few hours attempting to figure out why the Paypal Sandbox IPN Simulator isn't detecting a Content-type on my request back. I didn't modify any of the code where the request back is made, so it's odd that it's not going through correctly.</p> <p>There was a <a href="https://stackoverflow.com/questions/15422636/ipn-simulator-cannot-extract-response-no-content-type-found">similar question</a> back in March, though the answer he marked didn't seem to do the trick for me.</p> <p>Does anyone have any idea on why this is happening? Has this happened to anyone else recently?</p> <pre><code>public class PaypalIPN : IHttpHandler, IRequiresSessionState { public void ProcessRequest (HttpContext context) { //post back to either sandbox or live string strSandbox = "https://www.sandbox.paypal.com/cgi-bin/webscr"; string strLive = "https://www.paypal.com/cgi-bin/webscr"; HttpWebRequest req = (HttpWebRequest)WebRequest.Create(strSandbox); //Set values for the request back req.Method = "POST"; req.ContentType = "application/x-www-form-urlencoded"; byte[] param = context.Request.BinaryRead(HttpContext.Current.Request.ContentLength); string strRequest = Encoding.ASCII.GetString(param); strRequest += "&amp;cmd=_notify-validate"; req.ContentLength = strRequest.Length; //Send the request to PayPal and get the response StreamWriter streamOut = new StreamWriter(req.GetRequestStream(), System.Text.Encoding.ASCII); streamOut.Write(strRequest); streamOut.Close(); StreamReader streamIn = new StreamReader(req.GetResponse().GetResponseStream()); string strResponse = streamIn.ReadToEnd(); streamIn.Close(); ... </code></pre>
