how do i rewrite www.domain.com to another domain's /www/domain.com/index.php?

Question

i have this on my htaccess currently:

RewriteEngine on
RewriteCond %{REQUEST_URI} !^/www/
RewriteRule (.*) /www/$1/index.php

but i keep getting an error page

what im trying to do is to register a lot of domains for clients and just store all their websites' files on a folder named "theirdomain.com" on my domain's www folder.

Answer 1

Firstly you will never find www in the URI BEcause the URI is everything after index.php? so the uri will be index.php?/here/is/the.uri/string

I would look at HTTP_HOST

<IfModule mod_rewrite.c>
   RewriteCond %{HTTP_HOST} !^first-host.com$ [NC]
   RewriteRule ^(.*)$ http://new-host.com/$1 [L,R=301] #Send 301 so search engines know where to go.
</IfModule>
