CGI::Application + Net::HTTPServer

[gryphon]

Greetings fellow monks,

A while back, I posted about trying to wrap an existing CGI::Application web app inside a Net::HTTPServer script without making any modifications to the CGI::Application app's code. After some hacking, I think I've come up with something that mostly works. I've tested it for GET, POST, cookies, and redirects. It seems to do OK. There's one known bug: It doesn't save multiple cookies in a single request due to (what I think is) a bug in how Net::HTTPServer handles headers. So you can only save one cookie at a time for now.

#!/usr/bin/perl
use strict;
use warnings FATAL => 'all';
use Net::HTTPServer;

my $httpd = Net::HTTPServer->new(
    'port'     => 8081,
    'docroot'  => 'htdocs',
    'index'    => ['index.html', 'index.pl', 'index.cgi'],
    'log'      => 'STDOUT',
    'type'     => 'forking',
    'type'     => 'single',
    'numproc'  => 5
);

use CGI qw(-compile -oldstyle_urls);
use YourCGIApplicationModule;

sub yourapp {
    my $req = shift;
    my $res = $req->Response;

    $ENV{$_} = $req->Env($_) || '' foreach (keys(%{$req->Env()}));
    $ENV{HTTP_COOKIE} = join ('; ', map { $_ . '=' . $req->Cookie($_) 
+}
        keys %{$req->Cookie()});

    my $your_cgi_app = YourCGIApplicationModule->new({
        QUERY => CGI->new(
            ($req->Method eq 'GET') ?
                $req->Query : ($req->Request =~ /\n\W*\n([^\n]+)/) ? $
+1 : ''
        )
    });

    $res->CaptureSTDOUT;
    $your_cgi_app->run;
    $res->ProcessSTDOUT({ strip_header => 0 });

    my ($headers, @content) = split(/\n\n/, $res->Body);
    my $code = 200;
    foreach (split(/\n/, $headers)) {
        if (/^(.*?): (.*)$/) {
            $res->Header($1, $2);
            $code = $1 if (($1 eq 'Status') and ($2 =~ /^(\d+)\s/));
        }
    }
    $res->Code($code);
    $res->Body( join("\n\n", @content) );

    return $res;
}

$httpd->RegisterURL({
    '/yourapp' => \&yourapp
});

$httpd->Start;
$httpd->Process;
$httpd->Stop;

exit 0;

As always, I'm interested in any rewrites or suggestions you folks have. Thanks.
