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>]

'/products/whirlpool/1234567.html'

args=url_name=&model_nbr=*

(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
