[Q] RewriteMap

Post #1 of 4 (539 views)

Hi all,

it is the first time I'm trying to implement a RewriteMap, and although
I have some experience with regular expressions, something's going
wrong. Maybe some of you got the answer - so here's my prob:

apache 1.3.22 on Debian Linux 2.4.17

httpd.conf:

ServerName disp05
...
RewriteEngine On
RewriteLogLevel 4
RewriteLog /var/log/apache/disp05/rewrite_log

RewriteMap shortnames txt:/etc/apache/shortnames.txt
RewriteCond %{REQUEST_FILENAME} /\w+
RewriteRule (.*) ${shortnames:$1} [T=text/html,R=permanent,L]

As you may presume already, shortnames.txt looks like:
gesundheit http://disp05/app/jsp/categoryoverview_jsp/57285.html
hobby http://disp05/app/jsp/categoryoverview_jsp/85300.html
and so on

Now two strange things happen:
1. The RewriteCond doesn't match as it should do. For instance, if I
send a request for 'http://disp05/hobby' it doesn't match.
2. If I change the condition (to an expression that always matches)
applying the RewriteRule delivers 'http://disp05/' - which is absolutely
not what it should do.

Well, maybe all this happens just because it's friday, but nevertheless:
has anyone got an idea what's going wrong?

Many thanx in advance
Martin

Ok, forget about my post. mod_rewrite seems to be at least a little
buggy: doesn't understand \w, but [a-zA-Z0-9] instead...

Not all regex libraries are the same. Apache 1.3 uses HSRegex or your
system regex library (egrep-style) not perl regex.

As for your original question, please start by using the RewriteLog with a
high RewriteLogLevel to help you debug.

As I found out, apache doesn't tell much more with a loglevel higher than 4.
But thanx for the regex libs tip - I know them only from the perl side.
