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

ASP.NET is able to modify relative links found within the page and embed the Session ID in the URLs instead of storing it in a cookie.

Thus, as long as the user follows the path of links the site provides, session state can be maintained without using cookies. However, if the end user re-writes the URL, the session state instance will most likely be lost.
