Yes.

* If it is a true HTTP 30x redirect the followup client request will be
handled normally with regards to everything, including caching.

* If you are re-writing URLs the fetched object will be stored under the
mangled URL location.

logged when some new variant is needed and simply not-yet-cached. In
other words, a normal MISS is happening and nothing to worry about.
