Case sensitive URLs - how to make them insensitive?

Question

I'm struggling with mod_rewrite and .htaccess... All I need to do is make my URLs case in-sensitive. After couple of 500 internal server errors and a lot of googling a lot of stack overflowing I'm just looking for one working solution.

NOT working: Convert to lowercase in a mod_rewrite rule

RewriteMap tolower int:tolower
RewriteRule  ^([^/]+)/?$  somedir/${tolower:$1}

NOT working: Case Insensitive URLs with mod_rewrite

CheckSpelling on

All I need is simple not-case sensitive URLs :)

Answer 1

The following should work:

    <IfModule mod_rewrite.c>
    RewriteEngine on
    rewritemap lowercase int:tolower
    RewriteCond $1 [A-Z]
    RewriteRule ^/(.*)$ /${lowercase:$1} [R=301,L] 
    </IfModule>

If not, can you describe what's not working about the proposed solutions?
