All that is doable using mod_rewrite to set the mime-type based on the
path, but of course it's more work.  Depending on how many test cases
(pcaps) you have it may or may not scale.

I can't really comment on what we're working on, but I can say we
don't solve your stated problem today.  In general, client testing is
more difficult since the test harness (getting a random client
application to do what you want when you want it) tends to be very
specific and hard to generalize.
