Mod_rewrite - change url

Question

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

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

Examples:

http://example.com/ID at http://example.com/ID

http://example.com/ID/123 at http://example.com/ID/123

etc.

Answer 1

mod_rewrite has some internal functions that you can use to match. One is toupper , which converts letters to uppercase:

 RewriteMap uppercase int:toupper RewriteRule [az] %{uppercase:%{REQUEST_URI}} [L,R=301] 

Answer 2

I was looking to change case only identifier. This trick did:

 RewriteRule ^id(.*)$ /ID$1 [QSA,R,L] 

Answer 3

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