Answer 1

HTTP is a stateless protocol. All the web-based applications are also stateless.

When a request is send to the server, a connection is established between client and server. The server receives the request, processes the request and sends back the response and then, the connection will be closed.

If another request will be sent, after that, it will be treated as a new request and a new connection will be established.

In order to make HTTP stateful, we use session management techniques. So that, it uses the data coming from previous request while processing present request i.e, it uses the same connection for a series of client server interactions.

The session management techniques are:

1. hidden form field
2. cookie
3. session
4. URL-rewriting
