What are Apache Handlers in cPanel
Apache handlers control how your site’s Apache web server software 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.
You can configure Apache to use an existing handler to handle a new file type. To do this, manually add the handler and extension in this interface.
