Answer Posted / bhavesh kumar

Session tracking is the mechanism by which developer tracks the user actions across the session.
For example, an online video store must be able to determine each visitor’s sequence of actions. Suppose
a customer goes to your site to order a movie. The first thing he does is look at the available titles. When
he has found the title he is interested in, he makes his selection. The problem now is determining who
made the selection. Because each one of the client’s requests is independent of the previous requests,
you have no idea who actually made the final selection.

Their are 3 types of sesssion mechanism.
1)hidden form fields:-store information about session.
2)cookies:- a small piece of textual information sent by web apllication to client,sored on client and returned by the client for all request to the server.
3)url rewriting:- it is the concept of attaching a unique id.server attact this unique id in each url.when the client send requests it send back this id with the request also which helps the server to identify the client uniquely.
