Got it working by adding the appropriate @ OutputCache to the aspx page, but
now I have another problem:

How do I make sure a page is not cached?
MyBase.GetVaryByCustomString(context, custom) returns nothing, which should
mean that the page is not cached. but I can't get this to work. Any help
appreciated....

       Public Overrides Function GetVaryByCustomString(ByVal context As
System.Web.HttpContext, ByVal custom As String) As String
           Dim oParams As FAPCollection =
Utils.CreatePageParams(context.Request)
           Select Case custom
               Case "agent"
                   If oParams.Collection.Count = 2 Then
                       If oParams.ExistsKey("agentid") AndAlso
oParams.ExistsKey("opt") Then
                           Return "agent=" & oParams("agentid") &
oParams("opt")
                       End If
                   End If
           End Select
           Return MyBase.GetVaryByCustomString(context, custom)
       End Function

Thanks

Hi Buddy,
Did you find any solution to this problem. My problem is also same. the
Method "GetVaryByCustomString()" is not getting called. it is getting
called only twice. after that, control does not go to the method. Its
making me mad. I have this code in my .aspx file--
<%@ OutputCache Duration="100" VaryByCustom="ORGANIZATIONID"
VaryByParam="none"%>

Any help is appreciated.
Thanks
