復制代碼 代碼如下:

Session["id"] = user.id.ToString();
Session["name"] = user.name.ToString();
Session["pwd"] = user.password.ToString();
Session["time"] = user.LoginTime.ToString();
Session["authority"] = user.limits.ToString();

復制代碼 代碼如下:

protected void Page_Load(object sender, EventArgs e)
{

。。。。。。
}
}

復制代碼 代碼如下:

public void Clear(object sender, EventArgs e)

public void ClearClientPageCache()
{
//清除瀏覽器緩存
　　Response.Buffer = true;
Response.ExpiresAbsolute = DateTime.Now.AddDays(-1);
Response.Cache.SetExpires(DateTime.Now.AddDays(-1));
Response.Expires = 0;
Response.CacheControl = "no-cache";
Response.Cache.SetNoStore();
}

復制代碼 代碼如下:
