=head1 NAME
Perl::Critic::Policy::Freenode::ModPerl - Don't use mod_perl to write web
applications
=head1 DESCRIPTION
L<mod_perl|http://perl.apache.org/> is an embedded Perl interpreter for the
L<Apache|http://www.apache.org/> web server. It allows you to dynamically
configure and mod Apache. It is not a generally good solution for writing web
applications. Frameworks using L<Plack> (L<Web::Simple>, L<Dancer2>,
L<Catalyst>) and L<Mojolicious> are much more flexible, powerful, and stable.
A web application written in one of these frameworks can be deployed using a
Perl HTTP server such as L<Starman> or L<Mojo::Server::Hypnotoad>; by proxy
from Apache or nginx; or even run as if they were regular CGI scripts.
=head1 AFFILIATION
This policy is part of L<Perl::Critic::Freenode>.
=head1 CONFIGURATION
This policy is not configurable except for the standard options.
