HTML:

<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">

<META HTTP-EQUIV="expires" CONTENT="0">

PHP:

header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");

header("Cache-Control: no-cache, must-revalidate");

header("Pragma: no-cache");

ASP:

response.expires=0

response.addHeader("pragma","no-cache")

response.addHeader("Cache-Control","no-cache, must-revalidate")

JSP:

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

response.addHeader("Expires", "Thu, 01 Jan 1970 00:00:01 GMT");

或者:

1,   使用java提供的方法，在jsp或者servlet中都可以
<%
response.setHeader( "Pragma ", "No-cache ");
response.setHeader( "Cache-Control ", "no-cache ");
response.setDateHeader( "Expires ",   0);
%>
2,   使用HTML标记，如下面：
<HEAD>
<META   HTTP-EQUIV= "Pragma "   CONTENT= "no-cache ">
<META   HTTP-EQUIV= "Cache-Control "   CONTENT= "no-cache ">
<META   HTTP-EQUIV= "Expires "   CONTENT= "0 ">
