prg with rewrite_map does not seem to be working, maybe a bug

Hi All
I have been on these for 4 days now. No matter what I feed my simple perl
script in a simple rewrite_map setup it wont return any feedback when used
through apache. When used through comand line it works just fine.

Some background info:

debian:/var/www# apache2 -v
Server version: Apache/2.2.9 (Debian)
Server built: Jun 1 2009 17:44:04

####.htaccess
RewriteEngine on
RewriteCond ${dash2score:yes} yes
RewriteRule ^(.*)$ http://www.howstuffworks.com [P,L]d

or

RewriteEngine on
RewriteRule ^(.*)$ http://www.google.com/?index=${dash2score:yes} [P,L]

#####Apache2.conf
RewriteLog "/var/log/apache2/rewrite.log"
RewriteLogLevel 9
RewriteMap dash2score prg:/var/www/getIpStat.pl

##### getIpStat.pl

#!/usr/bin/perl
$| = 1;
while (<STDIN>) {
print($_."\n");
}

or
#!/usr/bin/perl
$| = 1;
while (<STDIN>) {
print($_."\n");
}

Well, the perl script simply returns whatever it is fed, so If I feed it yes
it returns yes, this would not work when I used the rewritemap with
rewritecond I would alwasy get no output. Since rewritecond would return
input='' as if rewritecond is not returning any input. The log showed:

192.168.0.189 - - [30/Jun/2009:18:00:08 +0300] [
192.168.0.1/sid#9500ba8][rid#b5f40078/subreq] (5) map lookup FAILED:
map=dash2score key=yes
192.168.0.189 - - [30/Jun/2009:18:00:08 +0300] [
192.168.0.1/sid#9500ba8][rid#b5f40078/subreq] (4) [perdir /var/www/]
RewriteCond: input='' pattern='yes' => not-matched
192.168.0.189 - - [30/Jun/2009:18:00:08 +0300] [
192.168.0.1/sid#9500ba8][rid#b5f40078/subreq] (1) [perdir /var/www/] pass
through /var/www/index.pl

Note the input='' above I.e. rewritecond did not show get any input from the
rewrite map

When I did try to use the rewritemap in the rewriterule as in the second
example it did not display anything as well in the result URL. The log
showed:

192.168.0.189 - - [30/Jun/2009:17:58:17 +0300] [
192.168.0.1/sid#9500ba8][rid#b61c4610/initial] (5) map lookup FAILED:
map=dash2score key=yes
192.168.0.189 - - [30/Jun/2009:17:58:17 +0300] [
192.168.0.1/sid#9500ba8][rid#b61c4610/initial] (2) [perdir /var/www/]
rewrite '' -> 'http://www.google.com/?index='

Note the index=' above

If I run the script from command line the following is shown:

debian:/var/www# ./getIpStat.pl
input1
input1

I enter input1 and it echoes input1

These are the permissions of the script:

-rwxr-xr-x 1 www-data root 352 2009-06-30 16:40 getIpStat.pl

and I did su to www-data and I was able to execute it successfully.

I really have no clue why the script is not returning any output when
invoked through apache.

Any clues ?

Thanks

There's no RewriteEngine directive set to "on" in your Apache2.conf?
In such a case the map program shouldn't be started during server
startup.

Not for the map type prg. But why don't you use the rules in your
apache2.conf? Since you're rewriting to a reverse proxy situation, you
could avoid the <directory> and <files> walk.

I tried in apache.conf however at that point the rewrite log was not showing
anything at all as if it was not being invoked....i dont have any
vhosts..just a regular installation.

Well I did apply the changes mentioned and prg started returning results.
However [P,L] now does not work the server throws

Request Error (invalid_request)

Your request could not be processed. Request could not be handled This
could be caused by a misconfiguration, or possibly a malformed request.
For assistance, contact your network support team.

At me, I did undo my changes but I am still getting that error..will
investigate logs.

Regards
