Is it possible to have an erroneous URL remain in the address bar while redirecting the user to a URL within my domain? I want www.domain.com/forum to be the actual site being served in all 404 circumstances but I don't want the referring URL to be rewritten (other than the domain portion, which is being done on the registrar level).
This is my current .htaccess
RewriteEngine On
RedirectMatch permanent ^/$ http://www.domain.com/forum/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* http://www.domain.com/forum/ [L,R]
