3.  A handler refers to an internal Apache representation of the action that is to be performed at the time
when a file is called. Usually, files have implicit handlers, depending on the file type. Generally, the files
are served by the server but there are certain types of files that are handled separately.
 It is possible to configure handlers explicitly, depending on either filename extension or on location,
without any relation to file type.
 Handlers can either be included in a module or be built into the server, or these can be added with the
Action directive.

5.  Apache handlers control the way in which a site’s Apache web server software manages certain types
of files and their extensions. CGI scripts and server-parsed files are handled by Apache.Apache can be
configured for using an existing handler for the purpose of handling a new file type. For this purpose,
you need to add manually the handler and the extension in the interface.
