If a user prefers to type userid and password each time they visit my site,
rather than permitting cookies, then I'm obviously not going to refuse
them their preferred operating mode.  Within-session, I'm presumably
going to carry state (user identification) in hidden input fields, in
this case, as it has to be within one reasonably brief "surfing session"
only; better to leave URLs nice and clean, so my regular users will be
encouraged to copy-and-paste them in enthusiastic word-of-mouth promotion
of my site by email, chat, SMS's, and voice conversations with friends.

Long URLs encoding id info are the least preferable option here, although,
if a way can be found to support them as a further _option_ (_without_
foisting them on the vast majority of users, which have no need for them),
they may be worth doing too.  (That's similar to the cookie-unrelated idea
of using POST normally, to get clean URLs for queries too, and GET as a
special option to allow "bookmarkable queries" as well).
