What is a Redirect?
Using the Redirect feature you can redirect a specific web page to another web page. The redirected web page would take the user to the intended web page and display the content on that page. This is also useful for making web page with a long URL accessible by redirecting it to a shorter URL which can be easily remembered by the visitors.
