   [code] public static bool doesUrlExist(string manifestUrl) { bool urlExists = false; Uri sourceUri = new Uri(manifestUrl); // Use Windows Authentication to check for a matching message directory HttpWebRequest request = (HttpWebRequest)WebRequest.Create(sourceUri); request.Credentials = CredentialCache.DefaultCredentials; request.Method = "HEAD"; try { // Retrieve the response from the server for the manifest.xml file HttpWebResponse response = (HttpWebResponse)request.GetResponse(); if (response.ContentLength > 0) // if the file is there { urlExists = true; } // Force the connection closed response.Close(); } catch (WebException) { return false; } return urlExists; } [/code] Can also say "if (response.ContentLength > 0)" that it is equal to true, can hard-code credentials, like this: [code] bool urlExists = false; string userName = "myUser"; string password = "Password"; string domain = "MYDOMAIN"; // Use Windows Authentication to check for a matching message directory WebRequest request = WebRequest.Create(manifestUrl); CredentialCache myCache = new CredentialCache(); myCache.Add(new Uri(manifestUrl), "NTLM", new NetworkCredential(userName, password, domain)); request.Credentials = myCache; // CredentialCache.DefaultCredentials; request.Method = "HEAD"; [/code] and instead of a response.Close(); at the end, you could encapsulate it all in brackets with a "using" statement. If your network sucks and you don't always get a valid reply, even though you should, you can use the function in a loop: [code] bool tester = false; // Use a function that will determine if the URL exists while ((tester == false) && (urlCounter < 51)) { tester = doesUrlExist(manifestUrl); urlCounter++; } urlCounter = 0; [/code] -Tom

   use System.net,System.web namespace

   HttpWebRequest req =(HttpWebRequest) HttpWebRequest.Create(@txtURL.Text.ToString());

   HttpWebResponse res = (HttpWebResponse)req.GetResponse();

   Response.Write(res.StatusCode.ToString());
