I am training in web developement and am learning about JSP & Servlets. I have some knowledge of HttpSession - I have used it in some of my sample projects.

In browsers I have seen the option to "delete cookies". If I delete the cookies it deletes the HttpSession also.

Are cookies and session the same? What are the differences between them?

jsp session servlets cookies

Google JSESSIONID. This will explain how the Servlet API initially uses URL re-writing and then, if cookies are enabled, cookies to manage sessions.

HTTP is stateless so the client browser must send the id of its session to the server with each request. The server, through whatever means, uses this id to retrieve any data for that session making it available for the lifetime of the request.
