SessionCookie bug in Enhydra 3.1.1

It seems that if I set the setCookieForNewSession to false, and at the same
time uses url-rewriting, the first time I hit Enhydra I don't get a session
cookie (which is good and as I want it), but the second time I hit Enhydra I
get a session cookie because I already have a valid session. Is this true?
How can I turn the session cookies off all together, if it's in the source
code, please point me to the correct place in the code.

Please I really need urgent help with this.
