Jay Balunas commented on RF-7906:
---------------------------------

I like this idea and the discussion, we should target something like this for 4.X.  Not sure if it will make it for 4.0 as we still have a lot of work.

Wanted to post like from forum - http://ajaxpatterns.org/Browser-Side_Cache

> When I do HTML/AJAX coding "by hand" (or using DWR or SeamWebRemoting) I can do something I have found to be almost impossible to do with Richfaces: AJAX Client Side 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.
