I've got an issue with redirection failing from my CGI::Application when running under mod_perl.

I'm very new to mod_perl so I could well believe that I've done something wrong. My configuration for Apache2 + mod_perl is very minimal:

ServerName ...

Alias /cgi-bin/ /mf/cgi-bin/
<Location /cgi-bin>
        SetHandler      perl-script
        PerlHandler     ModPerl::Registry
        PerlSendHeader  On
        Options         +ExecCGI
</Location>

This works for most of my application, and appears to improve response time significantly - however there is one problem. My redirections, as coded in the CGI::Application do not work.

I've pared this down to a minimal clone of my code - I have a base class implementing a redirect method, and I have a subclass which uses that to redirect a few times.

In plain CGI-mode this works. In mod_perl it gives me the following output direct to my browser:

redirect<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>200 OK</title>
</head><body>
<h1>OK</h1>
<p>The document has moved 
<a href="http://example.com/">here</a>.</p>
<hr>
<address>Apache/2.2.9 (Debian) PHP/5.2.6-2+b1 with
 Suhosin-Patch mod_ssl/2.2.9
 OpenSSL/0.9.8g mod_musicindex/1.2.2
 mod_perl/2.0.4 Perl/v5.10.0
 Server at mail-scanning.com Port 80</address>
</body></html>

Now here is my example code which exhibits the same problem:

#!/usr/bin/perl -w

use strict;
use warnings;
use CGI::Application;

#
#  Base package
#
package Base;
use base 'CGI::Application';

sub redirectPage
{
    my ( $self, $url ) = (@_);
    $self->header_add( -location => $url );
    $self->header_type('redirect');
}

#
#  Derived package
#
package Derived;
use base 'Base';


sub setup
{
    my( $self ) = ( @_ );
    $self->run_modes( homepage => 'homepage' );

    $self->start_mode('homepage');
    $self->mode_param('mode');
}

#
#  Dummy method to redirect to an external site.
#
sub homepage
{
    my( $self ) = ( @_ );
    return ( $self->redirectPage("http://example.com/") );

}


#
#  Instance script
#
package main;

my $derived = new Derived();
$derived->run();

Any clues, or tips are most welcome. Any more details I can provide just ask - this is all running upon libapache2-mod-perl2, as included in Debian.

Update: - Strangly using CGI::Application::Plugin::Redirect works correctly if I change my code:


package Base;
use base 'CGI::Application';
use CGI::Application::Plugin::Redirect;

sub redirectPage
{
    my ( $self, $url ) = (@_);

    return( $self->redirect( $url ) );
}

Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
