[RESOLVED] question on session

vang

"Sessions work by creating a unique identification(UID) number for each visitor and storing variables based on this ID. " - from the internet.

hi,
base on the above statement, i do not understand how did the server knows that the request was from my pc and not from other client?
Do the server capture client IP address when creating the UID for the session for each visitor?

I'm using WAMP, where can i locate the session file in the file directory when it was created?

Can we get/know the value of the UID?

Many thanks in advance for the guidance.

The default session handling stores the session id in a cookie on the user's computer.

The client provides the session ID (or UID, if you prefer). The typical way is by a cookie, though the query string and even a hidden form element can be used.

Yes, e.g., with [man]session_id/man.
