Re: [Dime] [dime] #43: Overstated guidance on session-ending requests.

Sorry for dropping this one. 

I don't agree.

To recap:

The opening of 3.1.4 says :

The paragraph to which I objected said:

When taken together, that says to me that we offer non-normative guidance that applications should throttle session terminating requests less aggressively, but that applications would define the exact behavior. I see nothing about local policy here.

The change that would make me happy would be to adjust the end disclaimer to say " The exact behavior ... is a matter of local policy, unless specifically defined for the application."

... and to change the first sentence of the second quote to say "As an example, session terminating requests might be throttled less aggressively..."
