Apache::Registry HEAD request also return document body

Hi all,

I have a problem with HTTP head requests and mod_perl. I have been
looking at the docs, searching google newsgroup archive but I couldn't
find anything thus you are my very last hope ;-)


In order to show what the problem is, I have set up two simple identical
'Hello World' type CGI scripts on my machine. One is running under
Apache::Registry, the other is running as a plain old CGI.

Here is what I get:

not_mod_perl test (plain CGI, everything works fine)
=================

[root@frogette /]# lynx --dump http://not_mod_perl
Hello World!

[root@frogette /]# lynx --dump -head http://not_mod_perl
HTTP/1.1 200 OK
Date: Fri, 23 Nov 2001 11:22:37 GMT
Server: Apache/1.3.19 (Unix) mod_perl/1.25
Connection: close
Content-Type: text/plain


mod_perl_test (mod_perl, headers are fubar)
=============

[root@frogette /]# lynx --dump http://mod_perl
Hello World!


[root@frogette /]# lynx --dump --head http://mod_perl
HTTP/1.1 200 OK
Date: Fri, 23 Nov 2001 11:24:50 GMT
Server: Apache/1.3.19 (Unix) mod_perl/1.25
Connection: close
Content-Type: text/plain

Hello World!


PROBLEM HERE
A head request should * NOT * return the body of the document


Obviously this is very wierd!

You can find more details on the config in the attached file.
Any ideas on what's going on?


Cheers,

This is the test script, test.cgi
=================================

#!/usr/bin/perl
print "Content-Type: text/plain\r\n\r\n";
print "Hello World!";



This is /opt/mod_perl/httpd.conf. It is included in my apache httpd.conf
