When I try non existent domains the GetResponse() method throws the "The remote name could not be resolved: 'domainname.com'" exception. Phil?

Check the URL using a regular expression. 2. Remove the Try/Catch 3. Check the .Status property of the Response If the Status property is 200 or 302 (Object moved), then the URL is valid, if it's any other status code it's invalid. I’d do it a little differently: -

If the Status property is 200 or 302 (Object moved), then the URL is valid, if it’s any other status code it’s invalid.
