Note: I cant use apache “virtualhosts” on my server, but I can use mod_rewrite.
I have two domains pointing to the same IP address.
They both go to the directory /public_html/www/.
What is the best way to make the “home” directory of one of the domains /public_html/www/somethingelse/?
Sounds like a shared-hosting plan: there are generally domain redirect tools provided to you which will allow you to point additional domains to existing paths under your main account:
domain 1: /public_html/www
domain 2: /public_html/www/domain2
domain 3: /public_html/www/domain3
