Mobile phone problem: Sessions not saved (no cookies?)

[eluser]simonmaddox[/eluser]
For mobiles, the best way to store persistent session data is to store a session id in the URL. We're using modified routing to build URL's like this:

http://domain.com/lsdkw5erddfh/some/page/here/

"lsdkw5erddfh" relates to a session in the database, where we store all of the data we need to about the user.

We don't use it for authentication, so you'd have to figure out how to prevent session hijacking better than we have...
