-------------8<---------- Start Bug Report ------------8<----------
1. Problem Description:
When executing a Perl CGI script with Apache2, i can write a
Status: 403 Custom Forbidden
header and the browser will see the response body i send. When executing the
same CGI script with ModPerl::Registry, the browser will also see the response
body.
However, if the response body is bigger than 8Kb, a filter seems to kick in and
substitute a custom response body, but only when executing the script with
ModPerl::Registry.
Normal CGI mode will work even for response bodies > 8Kb.
To recreate, add this file as /var/www/perl/test.pl
#! /usr/bin/perl -wT
my $response = <<_OUT_;
Status: 403 Custom Forbidden
Content-Type: text/html
_OUT_
$response .= "x" x 8192;
print $response;
and add the following fragment into /etc/apache2/sites-enabled/default
<Directory "/var/www/perl/">
AddHandler perl-script .pl
Options +ExecCGI
PerlResponseHandler ModPerl::Registry
PerlOptions +ParseHeaders
</Directory>
This test allows easy manipulation of the issue by altering the response body
size, the status line or the Handler.
