Don't censor ETag and Last-Modified under any circumstances.  Polipo
will survive an out-of-memory situation much more gracefully when
there is a strong validator.

Nothing serious should break if you censor IMS and friends
(If-None-Match etc.), but it will slow you down quite a bit -- Polipo
will detect every server as broken, and do a lot of slow things to
compensate.  So I certainly don't recommend it.
