: Mod_rewrite rule for wildcard subdomains? Sorry if this has been covered, I can't find anything on this specifically. I have wildcard subdomains on (*.mysite.com) I need a mod_rewrite expression

The $ operator will let you extract backreferences from matches in rewrite rules and the % operator will let you extract references from conditions.

RewriteCond %{HTTP_HOST} !www.mysite.com$ [NC] # Presuming you don't want to do www
RewriteCond %{HTTP_HOST} ^(.*).mysite.com [NC] # Catch subdomain
RewriteCond %{REQUEST_URI} !index.php [NC] # Don't rewrite if we already have
RewriteRule ^(.*)$ /users/index.php?user=%1 [L]
