URL Masking or a Frame Redirect is a type of domain forwarding that loads the forwarding destination page while keeping the URL the same.
If the domain domain.co.uk uses a Frame Redirect to http://www.google.co.uk, then when you view domain.co.uk in the browser, you will see the Google page while the address bar will still show domain.co.uk. This is the opposite from a HTTP Redirect which would forward all traffic for domain.co.uk to http://www.google.co.uk automatically.
Follow the steps below to create a frame redirect for your domain.
