a4j:rerenderCache to cache rerenders and reduce network and server use
----------------------------------------------------------------------

                 Key: RF-7906
                 URL: https://jira.jboss.org/jira/browse/RF-7906
             Project: RichFaces
          Issue Type: Feature Request
            Reporter: Francisco Jose Peredo Noguez


When I do HTML/AJAX coding "by hand" (or using DWR or SeamWebRemoting) I can do something I have found to me almost impossible to do with Richfaces: AJAX Caching. Currently there is no way to cache a previous AJAX rerender an re-play it again if the conditions for it to be re-played are met. This would be a huge performance improvement because it would save the application for going an fetching from the server information that has already been fetched in previous rereder calls.
So I propose the creation of a a4j:rerenderCache component (and auxiliar javascript functions) that make it easy to keep a client side cache of the state of the UI.
Please look at the referenced forum thread for a proposal on how this component could be used if implemented.
