HttpWebRequest timeout not working

Occasional Visitor

 

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
}
