Domain name masking allows you to show one URL in the browser’s address bar, while another website’s content is actually loaded. For example, when somebody opens your website, you can have yourdomain.com shown in the browser’s address bar while the actual site loaded will be yourOTHERdomain.com.
Confirm that your domain is configured under AddOn Domains. NOTE: If you have configured your domain under Aliases or Redirects you must delete those instances before you can add a domain as an AddOn Domain.
Log in to cPanel and look under “File Manager”.
Look for the folder listed for the domain and then the file named “index.html/index.php”. Otherwise, create a new one by Clicking on +File on the upper left. Next click the edit button in the navigation at the top of the File Manager
Paste the code below into the index.html file and click save. Be sure to define the Page Title, Description, Keywords, and of course the frame src. Once you have completed this you are done. The domain should now mask the URL.
<meta name=”description” content=”Description”>
<meta name=”keywords” content=”Keyword1, Keyword2″>
<frameset rows=”100%,0″ border=”0″>
<frame src=”http://yourotherdomain.com” frameborder=”0″>
