: Just another mod_rewrite question from the url xxx.yyy.site.com just need to redirect to xxx.site.com Thanks for the help, sorry I have no regex/rewrite foo.

This rule will redirect (301 Permanent Redirect) all incoming requests to xxx.yyy.site.com domain to xxx.site.com/ preserving the URL path (e.g. xxx.yyy.site.com/kitten?say=meow will be redirected to xxx.site.com/kitten?say=meow:
RewriteEngine On

RewriteCond %{HTTP_HOST} =xxx.yyy.site.com
RewriteRule .* xxx.site.com%{REQUEST_URI} [R=301,L]


This rule does not take into consideration HTTPS -- it will always redirect to HTTP. If it needs to preserve protocol as well (http -> http and https -> https), then you will need to have 2 rules (one for each protocol) and one extra rewrite condition for each rule (which will take protocol into consideration).
