禁用浏览器缓存：Cache-Control、pragma、expires

response.setHeader("Cache-Control", "no-cache");  		response.setHeader("pragma", "no-cache");  		response.setDateHeader("expires", -1);  		response.getWriter().print("hello hello!");

<meta http-equiv="pragma" content="no-cache">  	<meta http-equiv="cache-control" content="no-cache">  	<meta http-equiv="expires" content="0">
