Hi Everyone... Got one that has me stumped. I'm using Drupal as a CMS on a shared host and want to add a rewrite rule to send users from subdomain.example.com to www.example.com/subdomain while displaying the original address in the address bar. The CMS is already using a mod rule to make clean URL's for search engines and that is part of my confusion. Do I rewrite to a clean url or the original with the question mark? Anyway, here's the relevant bit of the .htaccess file that exists now: <IfModule mod_rewrite.c> RewriteEngine on RewriteBase / # Rewrite URLs of the form 'x' to the form 'index.php?q=x'. RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_URI} !=/favicon.ico RewriteRule ^(.*)$ index.php?q=$1 [L,QSA] </IfModule> I attempted to include: # subdomain rule RewriteCond %{HTTP_HOST} subdomain.domain.xxx$ RewriteCond %{REQUEST_URI} !subdomain/ RewriteRule ^(.*)$ subdomain/$1 When I attempted to include the above, it messed up the ability of the site to work at all. Clearly, I'm a mod rewrite neophyte so any help will be much appreciated! Korak
