推荐答案

在Application_BeginRequest事件中执行此操作. Session_start取决于会话时间.当会话仍在session_end时间开始时，它将起作用.

do this in Application_BeginRequest event. Session_start depend on session time. it work when session start still to session_end time.

Sub Application_BeginRequest(ByVal sender As Object, ByVal e As EventArgs)
       {
           // your codes here
       }
