Interface ExtensionHandler

public interface ExtensionHandler

Interface for a generic handler, to test incoming requests and screen them out or pass them through as appropriate.

Defines a single method, handle(HttpServletRequest, HttpServletResponse, ServletContext). Implementing classes will check parameters or cookies in the request and may either write to the response output stream directly, or pass the response object on to another request dispatcher.
