ApplicationDispatcher
final class ApplicationDispatcher implements RequestDispatcher(Code)
Standard implementation of RequestDispatcher that allows a request to be forwarded to a different resource to create the ultimate response, or to include the output of another resource in the response from this resource. This implementation allows application level servlets to wrap the request and/or response objects that are passed on to the called resource, as long as the wrapping classes extend javax.servlet.ServletRequestWrapper and javax.servlet.ServletResponseWrapper.
