No, you can vary the limit but you just have to make your My::ApacheHandler a little bit fancier.

package My::ApacheHandler;

use base 'HTML::Mason::ApacheHandler';

sub prepare_request {
  my $self = shift;
  my $r     = shift;
  my @args;

  ## <Location /foo>
  ## PerlSetVar MAH_POST_MAX 1024
  ## </Location>
  ## <Location /bar>
  ## PerlSetVar MAH_POST_MAX none
  ## </Location>
  my $post_max = $r->dir_config( 'MAH_POST_MAX' );
  unless( $post_max =~ /^none/ ) {
    push @args, POST_MAX => $post_max;
  }

  Apache::Request->instance( $r, @args );

  return $self->SUPER::prepare_request( $r, @_ );
}

Just checked this out...

works perfect!

Thanks ++

btw: maybe it's worth to implement this in Mason's src!?

--the good, the bad and the physi--

How can be this code adopted for Apache2? I'm using Apache2 together with Mason and session (MasonX::Apache2Handler as response handler and MasonX::Request::WithApache2Session as request class) and need to limit uploads too.

Trying to use described solution I get in most cases 500 response (Internal server error). It seems $m to be undefined :-(

When I tried to implement your code to do this, I get the following error: Can't locate object method "pnotes" via package "POST_MAX" (perhaps you forgot to load "POST_MAX"?)

package MyApacheHandler;

use base 'HTML::Mason::ApacheHandler';

sub prepare_request {
  my $self = shift;  
  my $r     = shift;

  my $post_max = 100; 

 Apache::Request->instance( $r, POST_MAX => $post_max );

 return $self->SUPER::prepare_request( $r, @_ );
}
  
1;

In the autohandler

<%init>
use MyApacheHandler;

my $apr    = MyApacheHandler::prepare_request($r,POST_MAX => 1);
</%init>

Any idea why I get this error?

Update: This is a newbie error and I solved it myself :)
