Well, for Application.cfc, here is my solution:
<cffunction name="onError" returntype="void" access="public" hint="">
<cfargument name="exception" type="any" required="true" hint=""/>
<cfargument name="eventName" type="string" required="true" hint=""/>
<!--- --->
<cfset var redirectUrl = cgi.scriptName>
<cfset var expirationDateTime = NULL>
<cfif arguments.exception.message IS "Session is invalid" AND
IsDefined("cookie.jsessionid")>
<cfset expirationDateTime = GetHttpTimeString(DateAdd("d", -1,
Now()))>
<cfheader statuscode="302" statustext="Moved Temporarily"/>
<cfheader name="location" value="#redirectUrl#"/>
<cfheader name="Set-Cookie"
value="JSESSIONID=;expires=#expirationDateTime#;path=/"/>
<cfelse>
<cfoutput>
<h3>Sorry, but there seems to have been an error:</h3>
<p>#arguments.exception.message#</p>
</cfoutput>
</cfif>
</cffunction>
I'm using for my own sites at CrystalTech... let me know if this works for you
