The "creation" of the id is implicit in the creation the session: the
session simply /has/ an id. You're try trying to avoid appending it to
the URL in all cases. The filter you referenced should do that.

The filter will prevent the session from appearing in URLs. Just note
that if a cookie-less spider (that's pretty much all of 'em) hits your
website and you use sessions without url rewriting, then every single
request from the spider will generate a new session (yikes!).

You may want to be careful about even creating sessions when you detect
a search spider.
