=head1 NAME
Plack::Handler::Apache1 - Apache 1.3.x mod_perl handlers to run PSGI application
=head1 SYNOPSIS
<Location />
SetHandler perl-script
PerlHandler Plack::Handler::Apache1
PerlSetVar psgi_app /path/to/app.psgi
</Location>
<Perl>
use Plack::Handler::Apache1;
Plack::Handler::Apache1->preload("/path/to/app.psgi");
</Perl>
=head1 DESCRIPTION
This is a mod_perl handler module to run any PSGI application with mod_perl on Apache 1.3.x.
If you want to run PSGI applications I<behind> Apache instead of using
mod_perl, see L<Plack::Handler::FCGI> to run with FastCGI, or use
standalone HTTP servers such as L<Starman> or L<Starlet> proxied with
mod_proxy.
