session variable timeout problem

[lwfg]

Trying to get a session variable to timeout by doing this but no luck. The variable testvar doesn't go away.
What am I doing wrong?

In application.cfm

<cfapplication name="test" sessionmanagement="yes" sessiontimeout="#createtimespan(0,0,0,10)#">
<cfparam name="testvar" default="a">

In other template

<cfif structkeyexists(session,'testvar')>
there
<cfelse>
gone
</cfif>

Meant to say <cfparam name="session.testvar" default="a">.

Never mind.
