Up until a couple days ago, I was using WP 2.2. With that version of WP, I was able to serve multiple domains with the same index.php file. In that index, I had "echo $_SERVER['HTTP_HOST']" php tags that would invoke the domain the browser was pointed at and then include the appropriate CSS. However, since I upgraded to WP 2.3.2, WordPress seems to be auto-forwarding back to my main domain. It's possible that my host changed the way they forward parked domains, but I think the odds of them doing it on the exact same day as I decided to upgrade to 2.3.2 are pretty slim. I'm guessing this is some security thing with WP trying to bind the content to the domain--can someone confirm this for me? And if I'm right, does anyone have any ideas as to how to stop this from happening?
