I think you must check the status code for the page URL, here http://en.wikipedia.org/wiki/List_of_HTTP_status_codes you can find status codes and what it means.

Subject: [Developers_For_Ever] Question: Check webpage availability...
Hi,
I have an issue, I want to check if a certain url is valide one or not, so I used:
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);//url: is the one I need to check its availability)
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
//and then I returned the: response.StatusCode.ToString(), it always return found!!! although the website isn't valide.
For instance, "http://www.google.co.uk" => Found
"http://www.googleeeee.co.uk" => Found !!!!!!!!!!!!!!!!!
Please, I need your opinions.
Thanks in advance.
Marwa Ahmad
