Benefit over old default is, that we get a short etemplate_exec_id giving better performance for ajax requests.
Drawback is currently poor garbadge collection only removing requests not used in 4 hours or which call egw_framework::window_close on server-side.
We can improve garbadge-collection by binding to window on(before)unload sending a (synchronious) request to server to remove concerned eT2 request.
- the etemplate_request object which stores the request data in the
a) session (as before) or
b) compressed and encrypted in the form transmitted to the user
Benefit of b) is that the session does not grow and the form can
be submitted as long as the session exists, as we need no garbadge
collection. Of cause more data needs to be submitt between
browser and webserver. b) is choosen automatic if mcrypt and
gzcompress are available, but can be turned off via setting
etemplate_request::$request_class = 'etemplate_request_session';
- static class variables instead of the before used global ones
--> This new version of eTemplate is fully backward compatible with 1.6!
