    Back Button Revisited asp.net 2.0

    I know, I know, I've read the posts, but I can't get it to work. Scenario is:
    Page 1 = registration page
    Page 2 = cc company page (I can't touch)
    Page 3 = return page for cc company
    Page 4 = my second page of receipt

    Pages 1, 3, 4, all use my master page, wherein I have:
    Protected Sub Page_PreRender( ByVal sender As Object, ByVal e As System.EventArg s) Handles Me.PreRender
    Response.Cache. SetCacheability (HttpCacheabili ty.NoCache)
    Response.Cache. SetExpires(Date Time.Now.AddDay s(-1))
    End Sub
    .........and... ..
    <head id="Head1" runat="server">
    <script language="javas cript" type="text/javascript">
    window.history. forward(1)
    </script>

    On each individual page for 1,2,3; I have:
    Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArg s) Handles Me.Init
    Response.Cache. SetCacheability (HttpCacheabili ty.NoCache)
    Response.Cache. SetExpires(Date Time.Now.AddDay s(-1))
    MyBase.OnPreRen der(e)
    Dim sb As New StringBuilder()
    sb.Append("<scr ipt language=javasc ript>" & Chr(10) & "")
    sb.Append("wind ow.history.forw ard(1);" & Chr(10) & "")
    sb.Append("" & Chr(10) & "</script>")
    ClientScript.Re gisterClientScr iptBlock(Me.Get Type, "clientScri pt", sb.ToString())
    End Sub

    And yet, when I go through the process and get to page 4, hit back button once, it takes me back to page 2.

    Please help,
    Janet

      Sorry it's hard to ready your post without the CODE tags, if you look to the right of the entry box the 3rd bullet down explains how to use them.

          So sorry, does this help?

          Page 2 = cc company page (I can't touch)

          Pages 1, 3, 4, all use my master page, wherein I have:
          Code:
          Protected Sub Page_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreRender
Response.Cache.SetCacheability(HttpCacheability.No Cache)
Response.Cache.SetExpires(DateTime.Now.AddDays(-1))
End Sub
          .........and... ..
          Code:
          <head id="Head1" runat="server">
<script language="javascript" type="text/javascript">

sb.Append("window.history.forward(1);" & Chr(10) & "")
sb.Append("" & Chr(10) & "</script>")
ClientScript.RegisterClientScriptBlock(Me.GetType, "clientScript", sb.ToString())
End Sub
          And yet, when I go through the process and get to page 4, hit back button once, it takes me back to page 2.
