My bad ... Its as Rich has already said. Its pretty nonsensical to
return a sessionId and a sessionExpires of 0 as the later indicates to
the consumer how long it needs to remember the former. If a session
expires and a new one has been started we expect the new one to be
returned in the response. FYI ... remember these are portlet sessions
not cookie (http) sessions. In the Java case the portlet session is
managed as a piece of the http session and hence its duration is
(typically) tied to that.

I agree with
you on caching. My question
is regarding session and I’m probably beating a dead horse. I just
wanted to know if returning a session having a session expires of 0 had
special
meaning to the consumer. I want to be clear on what options are
possible
if the producer has determined that the session has expired and the
implications:
1)
Return the
same session id with expires of zero –
consumer does not use session in future calls
2)
Return a new
session id with > zero expires –
the normal case (I presume)
3)
Throw
invalid session fault – causes consumer
to repeat last WSRP operation without a session id. I believe this is
to
force re-passing of templates once more if previously stated they were
stored in
session, etc.
Hopefully,
these options for returning
session and the implications are correct.

Setting
SessionContext.expires to zero
As further information, 0 is
commonly the setting when
one only wants validation level caching (checks). I.e. return a 0
expires
and an validation tag.

We explicitly chose
-1 for never expires such that 0
could have the normal meaning from a caching sense of already expired.

Setting SessionContext.expires to zero
Rich,
How
should setting SessionContext.expires to zero be interpreted by the
consumer:
a) an expired session b) same as unspecified c) other?
Thanks
