After this block of code executes, response will be the response stream from whatever was returned, no matter what the HTTP status code is. –Adam Maras Dec 7 '09 at 11:15 3 Remeber that HttpWebResponse is IDisposable and needs to be wrapped in using block, otherwise you will hit concurrent http request limit. –skolima Jul 9 '13 at 21:40 Instead of the using calling response.Cl

This has been working perfectly fine within my Development and QA environments but now that I have uploaded http://stackoverflow.com/questions/28396989/httpwebrequest-getresponse-returning-404-error it to my UAT server, I keep getting the following error: The remote server returned an error: (404) Not Found. The main difference between Dev/QA and UAT is that UAT uses SSL/HTTPS based URLs whereas Dev/QA uses HTTP. I introduced the following line of code to help progress me a little futher: ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback(AcceptAllCertifications); where AcceptAllCertifications always returns true but I still get my 404 error.

Join them; it only takes a minute: Sign up WebRequest.GetResponse does not return a 404 error up vote 0 down vote favorite We faced a strange issue. error 404 Until yesterday and for many years we have in use a small piece of code in our application to access a specific URL in order to check if a specific file exist inside: public static bool IsUpdateAvailable () { System.Net.WebRequest webRequest = System.Net.WebRequest.Create("http://site/updatefile.exe"); System.Net.WebResponse webResponse; try { webResponse = webRequest.GetResponse(); } catch (System.Net.WebException e) //If WebException exception thrown then couldn't get response from address { Console.WriteLine("This program is throw a WebException."+ "\n\nException Message the remote server :" + e.Message); if(e.Status == System.Net.WebExceptionStatus.ProtocolError) return false; } catch (Exception e) //If general exception thrown then couldn't get response from address { return false; } return true; } From yesterday the above code stops to return a 404 error if the checked file or the URL did not exist and thus always return true. We cannot explain from a c# view what happen. Any help will be appreciated. c# webresponse share|improve this question asked Oct 18 '13 at 16:14 Nikolas 256 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote Catch WebException and from it you'll be able to recover WebResponse Response, cast it into HttpWebResponse.
