The Remote Server Returned An Error 404 Not Found At System Net Httpwebrequest Getresponse
4.7 million programmers, just like you, helping each other. Join them; it only takes a minute: Sign up HttpWebRequest.GetResponse() returning 404 Error up vote 0 down vote favorite I have some code that calls HttpWebRequest's GetResponse() the remote server returned an error 404 not found asp net method to retrieve HTML from a URL and return it to the calling method. This has been working perfectly fine within my Development and QA environments but now that I have uploaded 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 remote server returned an error 404 not found wcf 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. I that people who previously had this error have been able to resolve the issue by merely ensuring the URI used for the HttpWebRequest doesn't have a slash at the end (see: Simple HttpWebRequest over SSL (https) gives 404 Not Found under C#) but this does not make a difference to me. I have now tried what was suggested at this post (see: HttpWebResponse returns 404 error) where I render the exception on the page. This bypassed the yellow-warning screen and gives me a bit more informtion, including the URL it is trying to get a response from. However, when I copy and paste the URL into my browser, it works perfectly fine and renders the HTML on the page. I'm quite happy therefore that the correct URL is being used in the GetResponse call. Has anyone got any ideas as to what may be causing me this grief? As said, it only seems to be a problem on my UAT server where I am using SSL. Here is my code to assist: public static string GetHtmlValues() { var webConfigParentUrlValue = new Uri(ConfigurationManager.AppSettings["ParentUrl"]); var destinationUrl =

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 { http://stackoverflow.com/questions/19454302/webrequest-getresponse-does-not-return-a-404-error Console.WriteLine("This program is throw a WebException."+ "\n\nException Message :" + 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. There you'll get a StatusCode you expect. share|improve this answer answered Oct 18 '13 at 16:19 Krzysiek Bronek 1463 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.
