I'm trying to write my mod_rewrite rules in my .htaccess file to fix the URL that shows up in the browser bar when visitors to to my site. I have a few options that I want my users to be able to enter. They should be able to enter something like:
and it should forward to
where bbb.org is a URL that I own that's pointing to the site now. I've already got a rule that removes www. from the front of either of those, and I have a rule that will forward aaa.xxx.yyy.edu to bbb.xxx.yyy.edu, but if you go to bbb.org, the URL in the browser bar shows up as bbb.xxx.yyy.edu.
