You are right. It does not make
sense to return back a pre-expired session if that is the interpretation.
When it’s not specified, it’s easy to make assumptions as to what
it means (use consumer default expiration, same as -1, same as invalid session fault,
never reuse this id again, etc. etc.).

SessionContext.expires to zero
yes, except for the 0 expires -- I would expect
the expires to be the duration of this new session. 0 can be returned but
it has no meaning regarding prior sessions and as such is nonsensical (though)
valid) for this id.

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.

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.

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