What do I need to setup within my .htaccess so that *1.domain.com shows the content of domain.com/sites/*1/ without redirecting? Please note, *1 means any possible combination, would redirect to that combinations subdomain..

Some examples:
http://test.domain.com/ = http://domain.com/sites/test/
http://new.domain.com/ = http://domain.com/sites/new/
