Where are sessions created?
The session itself resides in the server. For each request, the client transmits the session ID in a cookie or, if the browser does not allow cookies, the server automatically writes the session ID into the URL.
How do you check session is started or not?
Or: session_id(); // returns empty string session_start(); session_id(); // returns session hash session_destroy(); session_id(); // returns empty string, ok, but then session_id(‘foo’); // tell php the session id to use session_id(); // returns ‘foo’, but no session is active.
Why do sessions start?
session_start() creates a session or resumes the current one based on a session identifier passed via a GET or POST request, or passed via a cookie. When session_start() is called or when a session auto starts, PHP will call the open and read session save handlers.

What is session status?
session_status() is used to return the current session status. This returns an integer when you print it, since it is what PHP converts it into. So basically if you check for the 1 value, it’ll mean the session hasn’t been started, and i you check for 2 it means the session has been started.
What happens when you call session _ start ( )?
When one of your scripts calls session_start(), any other script that also calls session_start() with the same session ID will sleep until the first script closes the session. A common workaround to this is call session_start() and session_write_close() each time you want to update the session.
How is the session ID passed back to the server?
For subsequent requests, the PHPSESSID cookie is passed back to the server. When the server comes across the PHPSESSID cookie, it will try to initialize a session with that session id. It does so by loading the session file which was created earlier, during session initialization.
Where are sessionid values stored in ASP.NET?
If no SessionID value is supplied, ASP.NET starts a new session and the SessionID value for that session is sent to the browser with the response. By default, SessionID values are stored in a cookie. However, you can also configure the application to store SessionID values in the URL for a “cookieless” session.
