在开发中有时并不希望页面被缓存，特别是弹出式窗体，可以使用一下方法处理，将页面设置为不缓存。
方法一：在页面文件的HEAD中添加
<HEAD>
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Cache-Control" CONTENT="no-cache">
<META HTTP-EQUIV="Expires" CONTENT="0">
</HEAD>
方法二 ：在后端代码中添加，建议放在 Page_Load 事件中
Page.Response.Buffer = false;
Page.Response.Cache.SetNoStore();
C#清除页面缓存
private void SetPageNoCache()
{
Response.Buffer = true;
Response.ExpiresAbsolute = System.DateTime.Now.AddSeconds(-1);
Response.Expires = 0;
Response.CacheControl = "no-cache";
Response.AddHeader("Pragma", "No-Cache");
}
(1) Response.Buffer = true;
Response.ExpiresAbsolute = System.DateTime.Now.AddSeconds(-1);
Response.Expires = 0;
Response.CacheControl = "no-cache";
Response.AddHeader("Pragma", "No-Cache");
(2) HTML方法
<meta http-equiv="Pragma" content="no-cache"><meta http-equiv="Cache-Control" content="no-cache"><meta http-equiv="Expires" content="0">
(3) 重新调用原页面的时候在给页面传一个参数: href="****.ASPX?random()"
