设置浏览器不缓存

为了指示IE浏览器（客户端）不要缓存页面，服务器端的程序可以编写如下：response.setHeader(“Cache-Control”,“no-cache”);

response.setHeader(“Pragma”,“no-cache”);作用相当于上行代码，通常两者合用

publicstaticvoidsetNoCache(HttpServletRequestrequest,HttpServletResponseresponse){

if(request.getProtocol().compareTo("HTTP/1.0")==0){

response.setHeader("Pragma","no-cache");

}elseif(request.getProtocol().compareTo("HTTP/1.1")==0){

response.setHeader("Cache-Control","no-cache");

}

response.setDateHeader("Expires",0);

}
