             Summary: Mixed mode(Server+client) for state saving
                 Key: MYFACES-3779
                 URL: https://issues.apache.org/jira/browse/MYFACES-3779
             Project: MyFaces Core
          Issue Type: New Feature
            Reporter: Ertio Lew


How about having a mixed mode for state saving whereby state is initially kept 
on server for a configurable amount of time (so that fast frequent requests are 
served without transferring the state from client to server several times, the 
drawback with client side saving) & after that period of time if the page is 
still alive in browser but it is idle, a javascript request is triggered which 
asks the server for that state data & now it will be kept on client side, now 
the client & the server both know that state for this session is there on 
client. If the page has died & no request has been sent to server asking for 
state data till that period of time, then state data would be removed from 
server.

A further enhancement could be that you could set a fixed amount out of all 
memory on server that you want to allocate for state saving of all sessions. 
Till the time that quota remains, state is kept on server using that quota. But 
when that quota is over all the state information for further sessions is kept 
using client side state saving. Also a mixed mode.

Such mixed modes would be very helpful in improving performance, & better 
utilization of the server resources.
