How does a servlet handle GET and POST requests?
The HttpServlet abstract class, defined in the javax.servlet.httppackage, contains several methods that simplify interacting with HTTPrequests. Two of the methods take care of handling GET and POSTrequests. When you write a servlet, you should subclass HttpServletand implement the doGet() method to handle GET requests. Similarly,to handle POST requests, you would implement the doPost() method.
Both methods take an HttpServletRequest instance and anHttpServletResponse instance as arguments. The HttpServletRequestinstance contains all the information pertaining to the request,including any request parameters. The HttpServletResponse is used togenerate a response to the request.
