Problems with mod_rewrite

[Greg Allen <gallen@xxxxxxxxxxx>]

Hello,

I am having problems getting mod_rewrite to work for me.  I have a 
simple rewrite program
written in perl.  I have configured rewrite in the httpd.conf file and 
turned on logging. It looks
as though my map program is being called, but no value is being returned 
from the program (as
you can see from the rewrite.log.

I've included all the relevant files - httpd.conf, rewrite.pl, and 
rewrite.log.

Can anyone tell me what is wrong?

Thanks,

-- Greg

httpd.conf:

RewriteEngine on
RewriteLog /tmp/rewrite.log
RewriteLogLevel 9
RewriteMap mymap prg:/tmp/rewrite.pl
RewriteRule /foo/? ${mymap:$1}

/tmp/rewrite.pl:

#!/usr/bin/perl -i

# Disable buffered I/O which would lead to deadloops for the Apache server.

$| = 1;

while (<STDIN>) {
    s|^foo/|bar/|;
    print $_;
}

/tmp/rewrite.log:
