`cflogout` does not seem to clear the CFID and CFTOKEN values. Is `cflogout` only used with `cflogin`?

In this instance, I am not using `cflogin`. I am setting session variables because of the issues with `cflogin`. It worked before CF11 Update 7, however, CF11U7 seemed to resolve the `cflogin` double issue. Anyone else?

Is this all that I need? If so, it's not working.

```
<cfset structDelete(session, "CFTOKEN")>
<cfset structDelete(session, "CFID")>

```

What is the best way to logout using ColdFusion?
