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、xxx.aspx.cs中:
Context.Response.Cache.SetCacheability(HttpCacheability.NoCache);
比较倾向于第三种。
