Subject: Re: [wsia] [wsrp-interfaces] Another case for explicit session creation?

We do have to be careful about violating the current design also. This
essentially changes the session concept away from the current private
session to a shared session. The discussions on the telecons have settled
for providing an initEnvironment() type of operation that would allow any
such shared session initilization. One thought being explored is whether
having this as a separate portType would be a very clean way for a Producer
to indicate whether such an invocation is useful.

Subject: [wsia] [wsrp-interfaces] Another case for explicit session

I'd like to open another thread for the explicit session creation question.

In the standard portal situation, end users configure their own aggregate
views or "pages" of the available portlet services.  When an end user first
accesses their customized page, the portal needs to ask each of the
on the page to render their markup, assembles the page, and then presents
to the user.

Consider for the sake of argument that a theoretical page is composed of
five portlets, all of them remote portlets served by a single Producer.
portal has already created and configured the necessary entities.

In the portal startup case, the portal will send five individual requests
this Producer, each of them targetted at a different entity.  As there are
no sessions in effect yet, the Producer in turn creates a session for each
entity, and passes back the handle in the individual getMarkup response.

It would be more efficient for the portal, however, if there was just one
session created by the Producer, grouping all of the entities into a single
session.  Otherwise, the portal must now map the end user's request scope,
which in the standard http case is a single http session, to multiple
Producer sessions, and it must be certain to put the correct session ID
the performInteraction/getMarkup for each entity.

The portal could explicitly request a Producer session ahead of any calls
getMarkup, and pass this sessionID to getMarkup for all of that Producer's
