=head1 NAME
Apache2Kludge - mod_perl OutputFilterHandler for removing the Content-
+Length for CGI scripts  

=head1 SYNOPSIS

#In Apache 2.0 config
PerlModule Apache2Kludge
<Location /cgi-bin/SCRIPTNAME.pl>
    SetHandler perl-script
    PerlResponseHandler ModPerl::PerlRun
    PerlOutputFilterHandler Apache2Kludge
    PerlOptions +ParseHeaders
    Options +ExecCGI
</Location>


This module implements an Apache 2.0 output filter that removes the Co
+ntent-Length for scripts that 
worked under Apache 1.3 mod_cgi, but won't run under Apache 2.0


=head1 DESCRIPTION

This module implements an Apache 2.0 output filter that removes the Co
+ntent-Length for scripts that 
worked under Apache 1.3 mod_cgi, but won't run under Apache 2.0

When I encountered this problem, no one had a fix, and looking around 
+I found many other people having this same problem.
The problem seems to come from Apache sending the Content-Length prema
+turely.

The error generated in the logs when the script fails is 

(70007)The timeout specified has expired: ap_content_length_filter: ap
+r_bucket_read() failed

This can also be indicitive of other problems.

The Apache side of the configuration happens like so

#In Apache 2.0 config
PerlModule Apache2Kludge
<Location /cgi-bin/SCRIPTNAME.pl>
    SetHandler perl-script
    PerlResponseHandler ModPerl::PerlRun
    PerlOutputFilterHandler Apache2Kludge
    PerlOptions +ParseHeaders
    Options +ExecCGI
</Location>

=head2 EXPORT

None by default.
