Case-insensitive Clean URLs

[K_N]

Right now I'm using the simple

RewriteRule		^([A-Za-z0-9-]+)/?$		index.php?nav=$1 [L]

to remove query strings from my URLs, but I'd like it to be case insensitive, for example,

 

http://domain.com/foobar/ or http://domain.com/FOOBAR/

 

would point to the actual url

 

http://domain.com/index.php?nav=fooBar

 

Rather than having to use the exact case.
