  1.   

    这就看到了        Enumeration   e   =   hreq.getHeaderNames(); 
            
            System.out.println("=======================================");   
            while   (e.hasMoreElements())   
            {   
                    String   name   =   (String)   e.nextElement();   
                    System.out.println(name   +   ":"   +   hreq.getHeader(name));   
            }   
            System.out.println("=======================================");
