Class DHtmlUpdateServlet

java.lang.Object
  javax.servlet.GenericServlet
      javax.servlet.http.HttpServlet
          org.zkoss.zk.au.http.DHtmlUpdateServlet

All Implemented Interfaces:

java.io.Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

public class DHtmlUpdateServlet
extends javax.servlet.http.HttpServlet

Used to receive command from the server and send result back to client. Though it is called DHtmlUpdateServlet, it is used to serve all kind of HTTP-based clients, including ajax (HTML+Ajax), mil (Mobile Interactive Language), and others (see Desktop.getDeviceType().

Design decision: it is better to use independent servlets for /web, /upload and /view. However, to simplify the configuration, we choose not to.
