The Web application server invokes the servlet service() method upon receiving
an HTTP request targeted towards that servlet. This method in turn invokes the
appropriate HTTP-specific method based on the type of request.
HttpServletRequest is an input parameter and contains the HTTP protocol
specified header information. HttpServletResponse is an output parameter and
contains an HTTP protocol-specific header and can return HTML data to the
client. In our servlet we defined a doGet() and doPost() method so the servlet
can handle HTTP GET and POST requests. Both methods are identical; they call
the common processRequest() method, which deals with GET and POST
requests in the same way.
The initial section of the processRequest() method is shown in Figure B-23 on
page 361.
