在html头中加入以下3句话，可以防止大部分浏览器缓存<meta http-equiv="pragma" content="no-cache"> <meta http-equiv="Cache-Control" content="no-cache, must-revalidate"> <meta http-equiv="expires" content="Wed, 26 Feb 1997 08:21:57 GMT">或者js中加入类似下面的代码，让每次的链接都不一样var s=Math.random()*10; document.getElementById("checkCodeImg").innerHTML="<img src='/checkcode.jsp?rnd="+s+"'/ alt="设置html页面不让浏览器缓存的方法_html/css_WEB-ITnose" >";
