out.size is incremented each time Squid sends data to the client soket.

out.offset is how much the client side has read from the StoreEntry.
It's an internal counter, and indicates an offset into the original

Yes.

Yes.

No idea about that. out.size is also what is used as the information
source when reporting the reply size in access.log.
