=head1 NAME
Plack::Handler::Apache2 - Apache 2.0 handlers to run PSGI application
=head1 SYNOPSIS
<Location />
SetHandler perl-script
PerlResponseHandler Plack::Handler::Apache2
PerlSetVar psgi_app /path/to/app.psgi
</Location>
# Optional, preload the application in the parent like startup.pl
<Perl>
use Plack::Handler::Apache2;
Plack::Handler::Apache2->preload("/path/to/app.psgi");
</Perl>
=head1 DESCRIPTION
This is a handler module to run any PSGI application with mod_perl on Apache 2.x.
=head1 CREATING CUSTOM HANDLER
If you want to create a custom handler that loads or creates PSGI
applications using other means than loading from C<.psgi> files, you
can create your own handler class and use C<call_app> class method to
run your application.
package My::ModPerl::Handler;
use Plack::Handler::Apache2;
sub get_app {
# magic!
}
sub handler {
my $r = shift;
my $app = get_app();
Plack::Handler::Apache2->call_app($r, $app);
}
