Try this:
<cflock timeout="15" throwontimeout="No" scope="SESSION" type="EXCLUSIVE">
<cftry>
<cfscript>
variables.HoldCFID = session.CFID;
variables.HoldCFT = session.CFToken;
variables.HoldSID = session.SessionID;
variables.HoldURLT = session.URLToken;
structClear(session);
session.CFID = variables.HoldCFID;
session.CFToken = variables.HoldCFT;
session.SessionID = variables.HoldSID;
session.URLToken = variables.HoldURLT;
</cfscript>
<cfif (structKeyExists(cookie,'cfid') AND len(cookie.cfid) LT 3) OR
(structKeyExists(cookie,'cftoken') AND len(cookie.cftoken) LT 2)>
<!---MFC: {destroy the session if the token values are blank} --->
<cfset structClear(session)>
</cfif>
<cfcatch type="Any">
<!---MFC: {In case the session structure was cleared without saving
the variables first} --->
<cfset structClear(session)>
</cfcatch>
</cftry>
</cflock>
