如何将访问者数目周期性地保存？

<script LANGUAGE="VBScript" RUNAT="Server">

SUB Session-OnStart

...

Application.Lock

Application("visitors")=Application("visitors") + 1

' 增加访问计数

t-visitors = Application("visitors")

Application.UnLock

Session("VisitorID")=t-visitors

If t－visitors MOD 15 = 0 Then

Set FileObject = Server.CreateObject("Scripting.FileSystemObject")

Set Out=FileObject.CreateTextFile－(Application

("VisitorCountFilename"),trUE,FALSE)

' 周期性地保存到文件中

Application.Lock

Out.Write(t－visitors)

Application.UnLock
End If

...

END SUB

</script>
