RE: Caching POST requests

[Luca Rea]

I think that's not really correct, you can look at the cache like a map of 
request-digest and set-of-operations, instead of forward the entire post you 
could forward its digest and if it matches in the cache then its corresponding 
set of operations is taken running and the results returned.
Therefore for some tasks is reasonable receive results updated to the latest 
elaboration old some seconds or minutes.
