What you should actually do is make a temporary variable to the session
variable - this is because the lock doesn't close before the CFLocation
You should do it like this;
<cflock scope="SESSION" type="READONLY" timeout="10">
<cfset tmpVar=isDefined("session.stMyCurrentSessionStructure")>
</cflock>
<cfif not tmpVar>
<cflocation url="index.cfm?Fuseaction=#XFA.StartOver#" addtoken="No">
</cfif>
