We may end up having to go with the no caching policy and I had already
tested that and it worked but my boss prefers the timeout approach. Can you
think of any reason why it wouldn't work for me? I seem to be following the
instructions found in every place I've looked for setting up the
HttpCachePolicy. There wouldn't be a reason why testing it with the server
and the client being the same computer would affect anything would it?
Thanks,

I am using ASP.NET 2.0 and programming in C#. I am trying to make it so

the secure pages in my web application time out in the browsers cache
such
that hitting the back button won't show the page just because someone hit
the back button. I've seemingly done everything it says in the help
about
the Cache property of Response. The code I used is below and it still
seems to allow me to hit the back button and see the previous page event
after I have waited longer than the timeout period.
Thanks for any help you can provide,

this.Response.Cache.SetExpires(DateTime.Now.AddSeconds(5));
this.Response.Cache.SetCacheability(HttpCacheability.Public);
this.Response.Cache.SetValidUntilExpires(false);
if you have no problem with permanetly off cache then try this
this.Response.Cache.SetCacheability(HttpCacheability.nocache);
or check it

well,
then forgot cache use session time out, in each of your secure pages
add following code. it detect new session and redirect to another page
protected override void OnPreRender(EventArgs e)
{
base.OnPreRender(e);
if (Context.Session != null)
{
if (Context.Session.IsNewSession)
{
string sCookieHeader =
Page.Request.Headers["Cookie"];
if ((null != sCookieHeader) &&
(sCookieHeader.IndexOf("ASP.NET_SessionId") >= 0))
{
//optional
// if (Page.Request.IsAuthenticated)
// {
// FormsAuthentication.SignOut();
// }
Page.Response.Redirect("Sessiontimeout.aspx");
}
}
}
}
}
not in error. aspx page do some java script magic.
<HTML>
<HEAD>
<SCRIPT>
function back()
{
window.location="Sessiontimeout.aspx";
}
</SCRIPT>
</HEAD>
<BODY onbeforeunload="back()">
