I want my urls that contain uppercase characters to be redirected to lowercase url's. Unfortunatly i don't have access to the httpd.config file. So i tried this method to rewrite the urls with the htaccess file: http://www.askapache.com/htaccess/rewrite-uppercase-lowercase.html . But it adds extra / because it's a loop and also it doesn't work (504 error) when the url consists of more than two parts (ex www.mysite.com/part1/part2/part3/ )
How can i fix this or is there an other/better method?
If you look at your Apache error log (which is most likely huge thanks to this thing), you should see something along the lines of:

Everything goes well, until the path info postfix is applied. I am not sure why that is, but I know that applying the DPI flag to the 26 RewriteRules that transform uppercase to lowercase will most likely solve your issue.
# If there are caps, set HASCAPS to true and skip next rule
RewriteRule [A-Z] - [E=HASCAPS:TRUE,S=1]
# Skip this entire section if no uppercase letters in requested URL
RewriteRule ![A-Z] - [S=28]
# Replace single occurance of CAP with cap, then process next Rule.
