Make that 8. :P

Yes, like me. I was/am also confused by this setup.
It could be a lot clearer. Probably this setup is there for
backwardcompatibility reasons.
I didn't try all combinations, but this is how I think it works:
session.use_cookies
defines if cookies are used at all. If yes, a cookie is *possibly* used. In
false, a cookie is never used.
session.use_only_cookies
forces the use of cookies. The next setting is of no importance in that
case.
session.use_trans_id
If set to true, and session.use_only_cookies is set to false, url-rewriting
will be used if no cookiesupport is found.
At least that is what I found when using sessions. You milage may vary, etc,
etc..
I agree it is messy and these settings could use a little scrubbing.
