What are Sessions?

Answer Posted / manikanta.srinu

Web is Stateless, which means a new instance of the web
page class is re-created each time the page is posted to
the server. As we all know HTTP is a stateless protocol, it
can't hold the client information on page. If user inserts
some information, and move to the next page, that data will
be lost and user would not able to retrieve the
information. So what we need? we need to store information.
Session provides that facility to store information on
server memory. It can support any type of object to store
along with our custom object. For every client Session data
store separately, means session data is stored as per
client basis.
