thank you so much for your reply.  I think this definitely has me on
the right track.  what i need to figure out now is, is it Apache or
PHP that is switching the domain?  all the code uses relative links
(as far as i can tell... i didn't build this project, i inherited it,
so i'm figuring out the code as i go along).  Like I said in my
original post, I actually have 80 & 9090 pointed to the same dir on
the filesystem, and the same db.  However, as you so astutely pointed
out, the 9090 version doesn't switch to SSL, and I'm guessing that has
to do with our SSL cert?  I'm not sure what part of the code handles
that switch, but am currently digging through that.

Do you know if there's a way for PHP to set cookies for
*  In other words, have a cookie be valid for all
subdomains across a domain?  Or, do you have any input on where/who
might be switching the domain (apache, php, client-side?)?

Thanks again!
