session varibles not working

HI,

I am using a cf 9.1 app, and session variables are not working.  testpage.cfm sets a session.rage variable and has a button to go to page 2 where i cfdump the session and there is no rage variable defined there.  I am working with legacy code where apparently this used to work.  Help?  cfapplication tag below:

<CFAPPLICATION NAME="advapp" SESSIONMANAGEMENT="Yes" SETCLIENTCOOKIES="Yes" clientmanagement="Yes" APPLICATIONTIMEOUT="#CreateTimeSpan(0, 24, 0, 0)#" sessiontimeout="#CreateTimeSpan(0, 0, 45, 0)#">
