Application_OnStart 事件

Application_OnStart 事件发生在创建第一个新会话之前(当首次引用 Application 对象时)。

此事件放置在 Global.asa 文件中。

注意: 在 Application_OnStart 事件脚本中引用会话、请求或响应对象会导致错误。

Application_OnEnd 事件

Application_OnEnd 事件发生在应用程序结束时(当 Web 服务器停止时)。

此事件放置在 Global.asa 文件中。

注意: 无法在 Application_OnEnd 代码中使用 MapPath 方法。

语法

<script language="vbscript" runat="server">

Sub Application_OnStart

End Sub

Sub Application_OnEnd
. . .
End Sub

</script>
