RewriteCond %{QUERY_STRING} ^param=([a-zA-Z0-9_-]*)$ RewriteRule ^index\.php$ /ff/%1? [R,L]

Answer : htaccess change url to lowercase using RewriteMap

Hi,

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

Note that the RewriteMap directive can only be used in the httpd.conf and not in a .htaccess.

Cheers,
