mod_rewrite - change URL case

Question

Is there any straightforward way to change the case of any URL using mod_rewrite?

I thought this was pretty trivial... apparently not.

Examples:

ht

Answer 1

RewriteMap uppercase int:toupper
RewriteRule ^/(^/)*$ /${uppercase:$1}  [L]
RewriteRule ^/([^/]*)/(.*)$ /${uppercase:$1}/$2 [L]
