@Overrideprotected void doGet(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException{String type=req.getParameter("type");Enumeration es=req.getHeaderNames();System.out.println("Request type is : "+type);while(es.hasMoreElements()){//stem.out.println(es.nextElement());String header=es.nextElement().toString();String value=req.getHeader(header);System.out.println(header+":"+value);}System.out.println("================================================");}

首先是浏览器：
Request type is : broswer

httpclient:


Request type is : httpclient
Host:localhost:8888
User-Agent:Apache-HttpClient/4.3.1 (java 1.5)
Connection:keep-alive
Accept-Encoding:gzip,deflate

最后是casperjs:
Request type is : casperjs
Host:localhost:8888
Accept:text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language:zh-CN,en,*
Pragma:no-cache
