I am simply trying to redirect /?area=0 link to / .. hostname can be anything. I have tried:
redirectMatch 301 /?area=0 /index.php
RewriteRule ^/?area=0$ /index.php$1 [R=301,L]
Also tried with some little variations, but doesn't redirect or causes internal server error. Redirection only must happen when area is 0 and url does not contain other parameters.
