Variable sessiontimeout?

Hello all,

I have an area of a website that users log into.  Upon logging in, they are given a certain access level based off criteria in the datasource.  For regular users, the sessiontimeout in my application.cfm file looks like this: <cfapplication name="MemberSession" sessionmanagement="Yes" sessiontimeout="#CreateTimeSpan(0,0,20,0)#">.  Is there a way, based off the criteria in the datasource that assigns access levels (ALevel), to make the sessiontimeout longer for certain "privileged" users?  I tried the code below, but CF returned an error.

<cfif Session.ALevel neq 'SEC' or Session.ALevel neq 'EXSEC'>

<cfapplication name="MemberSession" sessionmanagement="Yes" sessiontimeout="#CreateTimeSpan(0,0,20,0)#">

<cfelse>

<cfapplication name="MemberSession" sessionmanagement="Yes" sessiontimeout="#CreateTimeSpan(0,0,90,0)#">

</cfif>

Thank you!
