This intece is intended to wrap servlets, but a servlet container can create RequestDispatcher objects to wrap any type of resource.

1.RequestDispatcher的API

1)void forward(ServletRequest request, ServletResponse response)

Forwards a request from a servlet to another resource (servlet, JSP file, or HTML file) on the server

2)void include(ServletRequest request, ServletResponse response)

Includes the content of a resource (servlet, JSP page, HTML file) in the response.

Defines an object to assist a servlet in sending a response to the client. The servlet container creates a ServletResponse object and passes it as an argument to the servlet's service method.

To send binary data in a MIME body response, use the ServletOutputStream returned by getOutputStream(). To send character data, use the PrintWriter object returned by getWriter(). To mix binary and text data, for example, to create a multipart response, use a ServletOutputStream and manage the character sections manually.

The charset for the MIME body response can be specified explicitly using the setCharacterEncoding(java.lang.String) and setContentType(java.lang.String) methods, or implicitly using the setLocale(java.util.Locale) method. Explicit specifications take precedence over implicit specifications. If no charset is specified, ISO-8859-1 will be used. The setCharacterEncoding, setContentType, or setLocale method must be called before getWriter and before committing the response for the character encoding to be used.
