can you explain in detail javax.servlet.http package
The javax.servlet.http package supports the development of servlets that use the HTTP protocol. The classes in this package extend the basic servlet functionality to support various HTTP specific features, including request and response headers, different request methods, and cookies. The abstract HttpServlet class extends javax.servlet.GenericServlet and serves as the base class for HTTP servlets. HttpServlet-Request and HttpServletResponse allow additional interaction with the client. Finally, since the HTTP protocol is inherently stateless, the package also includes HttpSession and some related classes to support session tracking.
