It would only cost you an extra request one time though.  After it is set,
you should be good.   You will have to test each request or store something
in the session to flag that the test has been done.  I'm guessing storing a
true/false value in the session to denote whether the test has been done
will be faster than testing the actual request.subdomains for "www" every
time.
