[users@httpd] Installing mediawiki with short urls

[Daniel Giron]

Hi,
I have installed mediawiki on an installation of Apache 2.2.0.
By default, wiki urls are of this form: http://hostname/wiki/index.php/$1
I wish to shorten it to http://hostname/wiki/$1 and have read several help documents on the web about this.
I used this RewriteRule: ^(.+)$ /index.php/$1 [L,QSA] inside the wiki directory in my httpd.conf .
Now, after getting 500 errors, I turned on RewriteLog with RewriteLevel 4, which gave me some output from mod_rewrite.
Unfortunately, what I saw was that it's been running the rule in a loop until getting to the limit of internal redirects (by default 10).
Does it mean that the L directive is not working correctly?
Or did I miss something when copying the exact example I saw on several sites?
I have also tried to change it around by adding /wiki/ in the beginning and such, but each time
it either didn't work at all, or it went into an endless loop.
Hope somebody can give me some insight into this problem.
Best regards,

Daniel
