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

[Ali Jawad <alijawad1@xxxxxxxxx>]

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
