just another mod_rewrite question

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.

Answer 1

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

RewriteEngine On

RewriteCond %{HTTP_HOST} =xxx.yyy.site.com
RewriteRule .* http://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).
