Object based caching about liboparl

[eFrane]

I'd rather vote for it should offer both object-based and request-based caching. My reasoning is that for some applications it might be very much okay to just keep raw request data around (mirrors for instance) as they don't actually care much about the contents whereas other applications that work with the object contents might not want to keep the request data around but do have the objects.

For simple mirroring you don't need liboparl, so the main mode for liboparl users will be object base caching. Object based caching can also improve performance significantly.
