提交网页的网页过期功能是怎么做的？

[wjq]

页面的page load部分加入如下代码
protected void Page_Load(object sender, EventArgs e)
{
Response.Expires = 0;
Response.ExpiresAbsolute = DateTime.Now.AddDays(-1);
Response.AddHeader("pragma", "no-cache");
Response.CacheControl = "no-cache";
}

[wuyq11]

<META content=no-cache>
<META http-equiv=Cache-Control content=no-cache>
<META http-equiv=Expires content=0>

Response.Cache.SetCacheability(System.Web.HttpCacheability.NoCache);
Response.Expires = 0;
Response.Buffer = true;
Response.ExpiresAbsolute = DateTime.Now.AddSeconds(-1);
Response.AddHeader("pragma", "no-cache");
Response.CacheControl = "no-cache";
