asp.net - What are cookieless sessions?

Question

In ASP.NET, I'm a bit confused about role of cookies in session state. Whats is the difference between normal session state and cookieless session state?

Answer 1

Normal session state involves providing a cookie. The cookie contains a session identifier which is used by the website to match visitors up with their respective session values.

Cookieless session state uses the same principles, but doesn't use cookies to pass the session identifier around. Normally, this is passed as a parameter on the querystring.
