本文详细介绍了HTML、ASP、PHP、JSP等常见Web开发语言中如何设置HTTP缓存头，包括no-cache、must-revalidate和指定过期时间等策略，以优化网站性能和减少服务器负载。

HTML:
<META HTTP-EQUIV="pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Cache-Control" CONTENT="no-store, must-revalidate">
<META HTTP-EQUIV="expires" CONTENT="Wed, 26 Feb 1997 08:21:57 GMT">
<META HTTP-EQUIV="expires" CONTENT="0">

ASP
response.expires=0
response.addHeader("pragma","no-cache")
response.addHeader("Cache-Control","no-store, must-revalidate")

PHP
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header("Cache-Control:
no-store, must-revalidate");
header("Pragma: no-cache");

JSP：
response.addHeader("Cache-Control", "no-store, must-revalidate");
response.addHeader("Expires", "Thu, 01 Jan 1970 00:00:01 GMT");
