You're damn right! I forgot this case where the ID could be used twice :-(
So we have no other choice but copying the ID into the session or HTTP
transaction, since it's possible to use it several times. At the same
time, I'm wondering if we should not also increment it for new sessions,
because for people who forward non-HTTP traffic, there's no unique counter.
What I'm thinking about is the following then :
- increment the global counter on each new session and store it into
the session.
- increment it again when dealing with a new request over an existing
session.
That way it would count each transaction, either TCP connection or HTTP
request. And since the ID would be assigned to the session, it would
remain stable for all the period where it's needed.
What do you think ?
