Interestingly tricky question. My immediate reaction was "no, you have
to do it all on IP+port", but that ain't strictly true. Snag is that the
real answer is far too complicated. I'd assume my immediate reaction and
leave us to fend for ourselves :-)

We'd get information that tells you something totally different from the
Host header, but could still (potentially) be used to distinguish

That was mine :-) Roy said you shouldn't croak if they're different.

BTW, chaps, I've started using STL recently. You really don't know what
you are missing. Did I ever mention that C++ is a really nice language?
