Unfortunately cPanel does not have a URL Frame feature. But
you can set up URL Frame forwarding for your domain on your own. For
that you will need to create a simple html page* with the following
<html> <head> <title> Type here anything you want </title> <!-- This text will be shown as name of the page --> </head> <frameset> <frame src="http://destination_domain.tld"> </frameset> <noframes>Your
browser does not support frames. Please click <a
href="http://destination_domain.tld"> here </a> to be
redirected automatically </noframes> <!-- This tag is required for old browsers. If browser does not support frames, end user will see a message indicated between <noframes>...</noframes> --> </html>
Simply change "http://destination_domain.tld" to the url you want to forward to and save the changes.
*Please note that you need to name this page index.html if it is the first (or the only) page for your website.
