CGI.pm not processing POST within AuthenHandler

[Michael L. Artz]

For some reason, CGI.pm (2.93) does not seem to parse POST data within a 
PerlAuthenHandler.  For example, the following:

sub handler {
   my $r = shift;
   my $q = new CGI($r);
   my @params = $q->param;
   $r->server->log->error("handler params are " . join "::", @params);
   return Apache::OK;
}
logs the paramter names correctly if the request is a GET, but not if a 
POST.  The same code works fine within an Apache::Registry script, which 
I assume will have the same behavior as a PerlResponseHandler.  I also 
attempted both the x-www-form-urlencoded and multipart/form-data POST 
types and neither worked.

Am I missing something that mod_perl is not doing till the response 
phase, like setting up STDIN?  I thought that this might have had 
something to do with an earlier thread 
(http://marc.theaimsgroup.com/?t=104992954600005&r=1&w=2), however I 
also tried adding:

$r->subprocess_env;
Apache->request($r);
to the handler to no avail.

Thanks
