I feel kinda stupid having to post this but years back I'd found and modified a small script that let me redirect multiple url's to separate folders, subdomains or domains.

Apparently, when the blackhole consumed my huge archives, I lost this.  Google has also since lost a lot of it's utility and stupidly and repetitiously provides worthless results to me that tell how to redirect multiple url's to a single site (duh).

I can't recall if the script I used was perl or php (I'm pretty sure it was one of those two) and I don't think I needed htaccess editing to get it to work.  At the time, I had a site that didn't officially support redirects like this but allowed me to run it.

Now I am back to scratching my head again for a simple way to do this.

Specifically for the present, I'd like URL "A" to redirect to Subdomain "A" and URL "B" to redirect to Subdomain "B".  Ideally, each redirect would show the originally entered URL (ideally...but I know this has issues).

It is important that it is cross-browser compatible.  I'm not looking for some antiquated javascript using depreciated values, etc.

Any ideas suggestions out there?

P.S.  This is a legitimate site--I just route personal stuff one way and business the other.  I'd like the two to stay completely separate is all.

Thanks!
