I do not think right now that exchanging this data or even

Preferences of the callout server will probably not change anything
here. Callout servers may like to make intensive use from preserved
data but be definition need to be prepared that the processor stops
to preserve more data; it has to handle that anyway. No need for a
special announcement I guess; it won't change the algorithm I guess.
Am I missing something? Do you know of examples where exhanging of
that information will make a difference?
A translation service will not use any of the data. An ad banner
stripping service will use all but the prefix data. The virus filter
service will use all the data. Ideally, the processor should not keep
5MB file to be translated but should keep the 5MB file being filtered.
How does the processor distinguish among these cases? Should the
processor assume that most data will be re-requested and preserve
aggressively until it receives a Wont-Use message?
