How to Add and Remove Apache Handler in cPanel?
Apache handlers control how your Apache web server software-that host your site- to manages certain file types and file extensions. Apache can handle CGI scripts and server-parsed files. The file extensions for these files include .cgi, .pl, .plx, .ppl, .perl, and .shtml. If you also wanted to process files that have .script extensions as Perl files, you could set up a custom Apache handler for your site.
