I suspect the problem is that the session cookies being generated
by PHP are being associated with the "teaching.cs.uml.edu" site,
so that the browser doesn't send the cookie when accessing the
"www.performamatics.org" version of the site.

When a new PHP session is created, the browser is given a cookie
that it sends with each subsequent request to the same server.
But browsers think of "same server" as being "same domain name" --
i.e., a browser won't send a cookie from "teaching.cs.uml.edu"
to a server at "www.performamatics.org" because the browser
treats them as being separate servers (as it is supposed to).
