php session.use_trans_sid

Question

I am not clear on the meaning and usage of php\'s session.use_trans_id .

On the online documentation, it says:

the run-time option session.u

Answer 1

if you enable "use_trans_sid" then the session id is attached to the URL everytime. Iam not sure what happens on an ajax request but i think it will be attached to.

And yes you need trans_sid when the user has cookies disabled, but its kind of insecure (think about someone is looking on your screen and writes down your session id? :-) ).
