Greetings apache users - I hope I selected the right list for this question:
I have a wierd mod_rewrite problem, that I need new eyes on.
What I try to do accomplish:
I am implementing “Userdirs” using mod_rewrite, with users in LDAP
The filepath is fetched from LDAP using a perl map program (with
ram-caching, for fast response, the programs does 20k responses in
0.2s, so it’s not a bottleneck)
Mod_rewrite config:
RewriteEngine on
RewriteLog /var/log/rewriter-log
RewriteLogLevel 9
#userdir via mod-rewrite via ldap via perl
RewriteMap lowercase int:tolower
# rewrite script with ldap lookup
RewriteMap uid-til-user prg:/home/scripts/users.homepage.pl
# rewrite on host match
RewriteCond ${lowercase:%{HTTP_HOST}|NONE} ^users\.example\.tld$
#get userid and path and rewrite
RewriteRule ^/~(.*?)/(.*?)$ /${uid-til-user:$1|fejl}$2
I have a simple static HTML page, with 20 images
<pre>
1<img src="image1.jpg">
2<img src="image2.jpg">
…etc…
19<img src="image19.jpg">
20<img src="image20.jpg">
</pre>
Fetching this page gives this rewritelog (| cut -d"/" -f4- for shorter line)
sid#80161a730][rid#8017ca0a0/initial] (2) init rewrite engine with
requested uri /~ccc2404/example/image11.jpg

'//mail/7/1/0/1/0/442//web/ccc/mail/7/1/0/1/0/442//web/ccc2404/example/image10.jpg'
sid#80161a730][rid#8017c80a0/initial] (1) go-ahead with
/home/www/data/2404/example/image9.jpg [OK]
image9 is loaded fine !
then comes TWO inits with SAME rid (8017c80a0)
the map program returns
//mail/7/1/0/1/0/442//web/ccc/mail/7/1/0/1/0/442//web/ccc2404/
//mail/7/1/0/1/0/442//web/ccc/mail/7/1/0/1/0/442//web/ccc2404/
But somehow the two answers get “mixed”
'/~ccc2404/example/image13.jpg' -> '/ml7101042/eb/ccc2404/example/image13.jpg'
'/~ccc2404/example/image18.jpg' ->
'//ai//////4/w/mail/7/1/0/1/0/442//web/ccc2404/example/image18.jpg'

[OK]
Why does this happen ? How is “rid” calculated ?
And How do I fix the problem ?
Any hints is appreciated – I am kind of stuck here.
