Convert and redirect URL in uppercase to lowercase using .htaccess

Question

I would like redirect a URL with uppercase characters http://localhost/A/B to a lowercase version http://localhost/a/b using the .htaccess file.

Using regex I can capture A and B but is it possible to convert them to lowercase?

In .htaccess

<IfModule mod_speling.c>
CheckSpelling on
</IfModule>

Tested, works, if you have the mod_speling enabled.

Or, in a serverwide httpd.conf:

RewriteEngine On
RewriteMap  lc int:tolower
RewriteCond %{REQUEST_URI} [A-Z]
RewriteRule (.*) ${lc:$1} [R=301,L]

	Added a working .htaccess version.. ;-) Of course, if you don't have access to httpd.conf, you probably won't have access to load the speling module.. will only lowercase if the folder/file is in lowercase on filesystem. – Grizly Sep 3 '10 at 10:43
	Yup it's working Grizly, thanks a million! – tintin Sep 3 '10 at 13:24
