Back Button issue after Logout in ASP.NET - onTick, Redirecting works on DEV but not on PROD environment

Posted on 2014-10-14

I've been experiencing a very strange behavior on PROD environment.  

I was told to tighten up the security that after logout, user cannot use browser back button to view pages.  Following the reference link below, I make it works on DEV that when user logs out, it clears session and redirects to login page.  However on PROD environment, on Chrome, Network tab, I see LogoutPage.aspx, status canceled in a loop,  the ticker keeps firing... and I can't do anything but close the browser.

Below is the message in the 'Headers'

<asp:Timer ID="Timer1" runat="server" Interval="1000" ontick="Timer1_Tick">  
<script type="text/javascript">

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Me.Master.FindControl("TopMenu").Visible = False
        Me.Master.FindControl("LeftMenu1").Visible = False
        Me.Master.FindControl("BreadCrumb1").Visible = False


 End Sub

Protected Sub Timer1_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        Response.Redirect("~/LoginPage.aspx", True)
End Sub

The problem is I don't have access to PROD so I don't really know what is happening here.  I could replicate the issue on DEV by redirecting to a page not found (LoginPagexxxx.aspx) but that doesn't seem like the issue because 'LoginPage.aspx' is there on PROD, when user is not logged in and tries to access a password protected page, it redirects the user to 'LoginPage.aspx' just fine.

Please tell me what the difference is between DEV & PROD?

Thanks in advance.

Never mind.  I solved it by removing the onTick event and put this in master page:
