Otherwise I get teh impression that you would have to wrap every conceivable page on the sub-directory site in the main directory with the redirect PHP script... ie, yes, if I request just the domain name your index page can redirect to a sub-directory... however if I request WidgetWorld.com/thispage.php the requests will go to MainDomain.com/thispage.php and will return 404 error if it doesn't exist follow my concern?
