[users@httpd] mod_rewrite problem: $1 and $2 not substituted into target url
Good morning Apache list,
I have a strange mod_rewrite problem, and I'm not sure how to solve it. I
have a RewriteRule that works correctly on one apache daemon, but doesn't
work when copied and pasted to the httpd.conf file of a second apache
daemon.
To state this differently, on the second apache daemon, mod_rewrite is
correctly matching the URL based on the regex, but it is not substituting
the back-references into the target URL.
The rule looks like this:
RewriteRule /products/(.*)/(.*)\.html$ /perl/
detail.pl?url_name=$1&model_nbr=$2
On the first server this successfully matches this request:
http://www.mydomain.com/products/whirlpool/1234567.html, and does an
internal redirect to /perl/detail.pl?url_name=whirlpool&model_nbr=1234567
On the 2nd (malfunctioning) server, it doesn't work -- although mod_rewrite
correctly matches the request to the rule, it doesn't substitute the values
inside the parentheses to $1 and $2 in the output URL. Here's what gets
written to the output of the RewriteLog on the 2nd server:
192.168.1.3 - - [26/Jan/2010:10:17:06 -0600] [
www.mydomain.com/sid#9094fec][rid#90a8b3c/initial<http://www.mydomain.com/sid#9094fec][rid%2390a8b3c/initial>]
(2) init rewrite engine with requested uri /products/whirlpool/1234567.html
192.168.1.3 - - [26/Jan/2010:10:17:06 -0600] [
www.mydomain.com/sid#9094fec][rid#90a8b3c/initial<http://www.mydomain.com/sid#9094fec][rid%2390a8b3c/initial>]
(3) applying pattern '/products/(.*)/(.*)\.html$' to uri
'/products/whirlpool/1234567.html'
192.168.1.3 - - [26/Jan/2010:10:17:06 -0600] [
www.mydomain.com/sid#9094fec][rid#90a8b3c/initial<http://www.mydomain.com/sid#9094fec][rid%2390a8b3c/initial>]
(2) *rewrite /products/whirlpool/1234567.**html -> /perl/
detail.pl?url_name=&model_nbr=*
192.168.1.3 - - [26/Jan/2010:10:17:06 -0600] [
www.mydomain.com/sid#9094fec][rid#90a8b3c/initial<http://www.mydomain.com/sid#9094fec][rid%2390a8b3c/initial>]
(3) *split uri=/perl/detail.pl?url_name=&model_nbr= -> uri=/perl/detail.pl,
args=url_name=&model_nbr=*
192.168.1.3 - - [26/Jan/2010:10:17:06 -0600] [
www.mydomain.com/sid#9094fec][rid#90a8b3c/initial<http://www.mydomain.com/sid#9094fec][rid%2390a8b3c/initial>]
(2) local path result: /perl/detail.pl
192.168.1.3 - - [26/Jan/2010:10:17:06 -0600] [
www.mydomain.com/sid#9094fec][rid#90a8b3c/initial<http://www.mydomain.com/sid#9094fec][rid%2390a8b3c/initial>]
(2) prefixed with document_root to /www/perl/mydomain/htdocs/perl/detail.pl
192.168.1.3 - - [26/Jan/2010:10:17:06 -0600] [
www.mydomain.com/sid#9094fec][rid#90a8b3c/initial<http://www.mydomain.com/sid#9094fec][rid%2390a8b3c/initial>]
(1) go-ahead with /www/perl/mydomain/htdocs/perl/detail.pl [OK]
Note the bolded sections of the log -- the values stored in $1 and $2 are
not substituted into the final URL. On the first server, these do get
substituted AND they get written to the rewrite_log.
Here's the relevant section of the httpd.conf file for the malfunctioning
Apache daemon:
RewriteEngine On
RewriteLog /var/log/apache-perl/rewrite_log.log
RewriteLogLevel 3
RewriteRule /products/(.*)/(.*)\.html$ /perl/
detail.pl?url_name=$1&model_nbr=$2
I thought it was possible that there were conflicts with other rules, so I
removed all the other RewriteRules and made sure that there were no
.htaccess files that applied to this request. I also tried hard-coding the
url_name param to "whirlpool", on the theory that mod_rewrite might be happy
with 1 substitution param, but no dice. In this case it still declined to
substitute "1234567" for $1. This httpd.conf file has no other virtual
hosts which might be causing a conflict.
Any suggestions as to what might be going on?
Thanks,
Chris

Hi Eric,
Yes, both are 1.3.
I don't have Apache2.pm -- the mod_perl2 module -- installed.
[root@data2 ~]# perl -MApache2 -le 'print mod_perl->VERSION'
Can't locate Apache2.pm in @INC (@INC contains: /www/perl/
/usr/local/lib/perl5/5.8.7/i686-linux /usr/local/lib/perl5/5.8.7
/usr/local/lib/perl5/site_perl/5.8.7/i686-linux
/usr/local/lib/perl5/site_perl/5.8.7 /usr/local/lib/perl5/site_perl .).
Thank you for taking the time to help!
Chris

Both systems are 1.3?

Hi Eric,
Thanks for the note. Both apache and mod_perl are up-to-date:
[root@data2 ~]# /usr/local/apache-perl/bin/httpd -v
Server version: Apache/1.3.41 (Unix)
Server built: Sep 2 2009 15:34:13
[root@data2 ~]# perl -Mmod_perl -le 'print mod_perl->VERSION'
1.31
Thanks,
Chris

Good morning Krist,
Thank you very much for your reply.
No, I don't have any <perl> blocks in the httpd.conf, although this is a
mod_perl enabled apache daemon.
Thanks,
Chris

You are not using any <perl> sections by chance, are you?
