Response.Expires = -1意思
Response.Expires = -1是什么意思啊
Response.expires 该属性指定了在浏览器上缓冲存储的页，距过期还有多少时间
1、在Asp页面首部加入Response.Buffer = True Response.ExpiresAbsolute = Now() - 1 Response.Expires = 0 Response.CacheControl = "no-cache" Response.AddHeader "Pragma", "No-Cache"
2、在HtML代码中加入<HEAD><META HTTP-EQUIV="Pragma" CONTENT="no-cache"><META HTTP-EQUIV="Cache-Control" CONTENT="no-cache"><META HTTP-EQUIV="Expires" CONTENT="0"></HEAD>
3、在重新调用原页面的时候在给页面传一个参数Href="****.asp?random()"
4、<body onLoad="javascriptocument.yourFormName.reset()">
5、Content.Response.Cache.SetCacheability(HttpCaxheability,NoCache);
补充：网页制作,设计基础
