I have a problem getting the location header from WebResponse:
private CookieContainer _cookieContainer = new CookieContainer(); ... HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(uri); webRequest.Method = "POST"; webRequest.Referer = "www.xxxxx.sk"; webRequest.Proxy = GetSystemProxy(); webRequest.AllowAutoRedirect = false; webRequest.CookieContainer = _cookieContainer; webRequest.ContentType = "application/x-www-form-urlencoded"; webRequest.KeepAlive = false;
When I use the Tamper data plugin in Firefox - I get what I want:
Location = HTTP://www.xxxxx.sk i9 = 3522a42d0207
But looking at HttpWebResponse.Headers does not contain this header (although 90% of the headers received are the same as with firefox)
I tried to install. Expect to get the server to provide me with this header, but I got an error 417 The wait failed.
The reason I need this header is because it has the session identifier that I need for further requests (the website has double protection - cookies + session identifier in the URL)
I don’t understand that by default, HttpWebRequest will follow the redirects , so if the server sends the 301/302 status code, a new request will be issued to retrieve the resource using the Location header, therefore, as soon as this final resource is received, the response will no longer Location header. But if I set AllowAutoRedirect to false , why the title is not displayed?
