   [.net] WebRequest Exception
  Im trying to get the response of a web request by calling the GetResponse() method after creating (succesfully) the WebRequest.However, one day, all of a sudden, after it had been working earlier, I get a "ReceiveFailure" WebException.Any Ideas?   
  Could you please post some code so we can take a look?   ;  WebRequest req;WebResponse res;req = WebRequest.Create("https://nexus.passport.com/rdr/pprdr.asp");res = req.GetResponse(); (Throws WebException : ReceiveFailure)   ;  Hey, I'm not sure because your code looks different than I expected, but I do have some web request code that I know works quite well in a testharness that I wrote once.Let me know if you have questions (I just copied it from inside a method, so I hope that I got all of it in there.)You'll have to write your own logging routines or replace them with writelines or whatever.   string link = "http://www.yahoo.com";   DateTime dtnow = DateTime.Now;   //Perform the request for the web page here.   try   {System.Net.HttpWebRequest myRequest = (System.Net.HttpWebRequest)System.Net.HttpWebRequest.Create(link);  // Initialize the WebRequest.myRequest.AllowAutoRedirect = true;myRequest.MaximumAutomaticRedirections = 100;myRequest.MaximumResponseHeadersLength = 1024;using (System.Net.HttpWebResponse myResponse = (System.Net.HttpWebResponse)myRequest.GetResponse()) // Return the response. {  try  {    //Perform validation here.    if (myResponse.StatusCode == System.Net.HttpStatusCode.OK)    { //Read from the page here. using (Stream receiveStream = myResponse.GetResponseStream()) {   try   {//Pipe the receiveStream into streamReader to make this a little easier.using (StreamReader sr = new StreamReader(receiveStream, Encoding.UTF8)){  try  {    //Read the content off of the page with a stream    string actualResult = sr.ReadToEnd();    bool result = false;    //Validate that some content actually did get returned.    if (actualResult.Length > 0) result = true;    //Report resultif (result == true) Logger.LogSuccess("Passed :: Link successfully requested :: " + string.Format(Logger.LinkPrintFormat, link));    else Logger.LogError("Failed :: Unable to request link :: " + string.Format(Logger.LinkPrintFormat, link));    //Report verification results    if (result == true)  System.Console.WriteLine("process stuff here");  }  finally  {    sr.Close();  }}   }   finally   {receiveStream.Close();   } }    }    else Logger.LogError("Failed :: " + link);  }  catch (Exception ex)  {    Logger.LogError("Failed :: " + link);    Logger.LogError(ex);  }  finally  {    if (myResponse != null) myResponse.Close();   // Close the response to free resources.  }}  //using myResponse   }   catch (System.Net.WebException ex)   {if (ex.Message == "The remote server returned an error: (400) Bad Request."){  Logger.LogError("Failed :: " + link);  Logger.LogError(ex.Message);}else{  Logger.LogError("Failed :: " + link);  Logger.LogError(ex.Message);}   }   TimeSpan elapsedTime = DateTime.Now.Subtract(dtnow);   if (elapsedTime.Seconds > 10)Logger.LogInformation("Elapsed Time: " + elapsedTime.Seconds + " seconds"); [Edited by - BradSnobar on June 14, 2006 8:52:42 PM];  Thanks, Ill give it a try :)One more question though, HttpUtility seems to be a well known class supplied by the System.Web namespace. I cant seem to be able to find it :S   ;  THe HTTPUtility Class should indeed be in the System.Web namespace. There's only one thing I could think of if it is not there:You need to add a reference to the System.Web Assembly. Although I guess you've done this already. If it is an ASP.NET project it should have been added at the project creation by Visual Studio.   ;  Nop, it aint there, haha.Yes, I added the Web namespace, and I do see that objects from the namespace are indeed there. However, the HttpUtility isnt there. Even when I use the object browser to browse for the class I find it, but I cant find it when typing the actual code.Its extremely weird.   ;  Sometimes intellisense is broken.That might be what you are encountering?
