| 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.
