You have a long site URL but want to use a shorter URL, how is it done?
It is using the HTML frame to mask the destination URL and keep the originate URL in the browser.
You would create a site with a short URL and on that site you create an index.html that contains the HTML code as shown below.
Here is the HTML code that make the URL masking work!
Note: the above "frame src" use either the domain name or your IP address for your site.
