The URL is never written to the cache, but the object may in some
special conditions.

The objects are removed as soon as the request completes.

The URL never enters the memory or disk caches. The object is kept under
a private identity for the whole duration of the request.

Not really, but Squid-2.4 should ignore such cached objects...
(earlier Squid versions will give cache hits)

Not at this time no, but you are free to implement something like that
if needed.
