3.2 Deriving from rwsf::HttpServlet

An HTTP servlet handles standard HTTP requests. Although HydraExpress contains a generic servlet class, in practice, most servlets provide Web services or deliver content to Web browsers. Therefore, most servlets derive from rwsf::HttpServlet.

The HelloWorldExample servlet receives an HTTP GET request from a client and returns a fixed response. The sample below shows the outline of the HelloWorldExample servlet class:

// Simplified from HelloWorldExample.h

#include <rwsf/servlet/http/HttpServlet.h>

class HelloWorldExample : public rwsf::HttpServlet {
   // Section 3.4 discusses methods for the servlet
 };
