模式窗体，是通过querstring传值的，当编辑某条信息的时候，遇到弹出的模式窗体老是调用缓存的值的问题，最终还是找到了解决方案，现总结如下：
html:
在<head></head>之间加上：
<meta http-equiv="Expires" content="0">
<meta http-equiv="Cache-Control" content="no-cache">
<meta http-equiv="Pragma" content="no-cache">
ASP:
<%
Response.Expires = -1
Response.ExpiresAbsolute = Now() - 1
Response.cachecontrol = "no-cache"
%>
//asp.net中,在窗体的PAGE_LOAD事件中加上Response.CacheControl = "no-cache";
如下:
protected void Page_Load(object sender, EventArgs e)
{
Response.CacheControl = "no-cache";
if (!Page.IsPostBack)
{
this.d1.Value = DateTime.Now.ToString();
}
}
PHP:
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header("Cache-Control: no-cache, must-revalidate");
header("Pragma: no-cache");
JSP:
response.setHeader("Pragma","No-Cache");
response.setHeader("Cache-Control","No-Cache");
response.setDateHeader("Expires", 0);
