How does a servlet handle GET and POST requests?
The HttpServlet abstract class, defined in the javax.servlet.http
package, contains several methods that simplify interacting with HTTP
requests. Two of the methods take care of handling GET and POST
requests. When you write a servlet, you should subclass HttpServlet
and 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 an
HttpServletResponse instance as arguments. The HttpServletRequest
instance contains all the information pertaining to the request,
including any request parameters. The HttpServletResponse is used to
generate a response to the request.
