RE: [wsrp] Action item: CR313 (cookie advice)

I would rather that the statement be
limited to something like (Note: it was section 3.11 in v1, but is now
section 3.12):

"The requirements in Section 3.12
regarding Consumer processing and resupplying of cookies is applicable."

The requirements in Section 3.12 is
where any changes to reflect tolerance of concurrent requests need to be
applied. Any suggestions for that section?

“Consumers MUST process and resupply
such cookies, as per Section 3.11, in further requests which logically
follow and are not concurrent with the cookie setting reply.”

 

Which implies the producer must somehow
be able to cope with concurrent requests that carry the stale cookie!

I would rather not introduce a conformance statement in the fault section
that simply says other conformance statements apply. I would note that
the discussion in 3.12 does apply ... Andre, perhaps you could suggest
updated language for that section if you think it is overly restrictive.

I believe you may still get further requests from the consumer with

stale cookies just after the producer returns (sets) a new cookie. The

producer can accept these or may fault but it means that the "MUST"

wording below needs to take into account such concurrent requests. 

I would also like to see this relaxed to allow for concurrent

(distributed) consumers where returned cookies may take some time to

propagate before they are available for use on all future requests.

Regards,

Andre

At the F2F, some people wanted to check if various proxy/cluster systems

can implement the guidance. Here is the guidance.

"However, since such reprocessing usually incurs additional processing

and network overhead, Producers are encouraged to process the request as

usual and return new cookies along with the response. Consumers MUST 

process and resupply such cookies as per Section 3.11."

AFAIK, this guidance is inline with how various cluster/proxy systems 

behave. Depending on how load-balancers are setup, they eigher create a

new cookie when a request without a cookie is detected, or modify the 

cookie set by a application server node to include some form of node 

identifier.

This is a reminder for folks to check with their teams.

Subbu
