HttpWebRequest timeout not working

 

When I disconnect the ethernet, the request just hangs.

 

 

 

                    HttpWebRequest request = (HttpWebRequest )WebRequest.Create(WebAddressPreAmble + WebAddress + WebAddressQuery); // Create(sQuery);
                    request.Credentials = CredentialCache.DefaultCredentials;
                    request.Timeout = 10000;
                    request.ReadWriteTimeout = 1000;
                    // Get the response.
                    HttpWebResponse response = (HttpWebResponse)request.GetResponse();
                    // Display the status.
                    if (response.StatusDescription.Equals("OK"))

    You have no exception handling so it might be throwing an error and the code hanging elsewhere.

    HttpWebRequest can return a WebException which is not caught as a normal exception. Also, when using external resources you should always have try/catch blocks.

    try
    {
    // web request code
    }
    catch (WebException e)
    {
    if (e.Status == WebExceptionStatus.Timeout)
    {
    // handle timeout
    }
    else throw; // optional
    }
    catch (Exception ex)
    {
    // handle exception
    }
