Re: [wsrp] resource cachability - templates

[Rich Thompson <richt2@us.ibm.com>]

The case is actually worse than that!

If the Consumer is producing true templates,
some encoding of state is going to have happened during the production
of the template. Thus the Producer could eliminate the portlet's portion
of state relative to the "full" semantics, but it would be unable
to eliminate the state of other portlets.

My preference would be to keep the base
going into v2 as simple as we can (i.e. the current proposal) and introduce
an extension which carries 4 additional templates. This would allow Consumers
and Producers who truly move this processing to the Producer to provide
full functionality without placing the burden of requiring four additional
templates on all Consumers.

You bring up a very good point.

Per the current proposal, during producer URL writing, the producer can
only encode state specific to the portlet. The default behavior would be
similar to that of "full", i.e. the producer will replace tokens
like 
portletHandle, sessionID etc.

If the portlet (e.g. in a JSR286 scenario) wants to use something other
than full, the only choice that the producer has is not replace those 
tokens. The producer can not differentiate between "portlet"
and "page", 
and this gap needs to be filled in the proposal.
