HTTP protocol is stateless, we need to add Session Tracking to make the client-server relationship more stateful. Session tracking is important for tracking communication in applications. In this article, we will discuss what is the importance of session tracking in Java. You can learn all about Java web development from the advanced Java j2ee training in Kochi.

Here are the different types of Session Tracking techniques used in Java.

1. Cookies
2. Hidden Form Field
3. URL Rewriting
4. HTTP Session

What is a Session?

A session simply means a particular interval of time from the user logging into and logout.

Working of Session

1. When the user sends a request on the webpage.
2. Our browser sends the request to the corresponding web server using HTTP.
3. The server analyses that there is no “session-related information” in the request. So that it needs to build a new session.
4. It helps the user to communicate with the server through a safe data transfer.

Cookies

A cookie is a unique ID that is assigned to clients when they visit a website for the first time. When this client reconnects to the server, it will send the cookie that was previously provided by the server. The server will then recognize that the user is the same.

Hidden Form Field

When sending a request to the server, hidden form fields are used to insert information, such as a unique ID. These fields are not directly visible to the user, but the unique ID is sent as part of each request to the server, allowing the server to acknowledge the client.

URL Rewriting

When URL rewriting sends a request to the server, it appends a unique session ID into the URL itself. Users can see the session ID because it is part of the URL.

HttpSession

The HttpSession object represents a user session. The HttpSession interface is used to establish a session between an HTTP client and an HTTP server. A user session is a collection of information about a single user that spans multiple HTTP requests.

Every software should be followed session for its proper communication and maintaining an individual session for users. You can learn more about Java for full stack development from the best Java online training in Kochi.
