Indeed it does. But in all the instances I just saw (quick review), it was
also doing a cfset, which absolutely MUST be locked.
See, what I want to do is simply this:
<cfif isDefined("Session.isLoggedIn")>
<cfset Request.isLoggedIn = "y">
<cfelse>
<cfset Request.isLoggedIn = "n">
<cfset Client.email = "">
</cfif>
Session.isLoggedIn is set within a cflock (obviously) on a valid login.
After that, I include the above code in my Application.cfm and (maybe) do
not have to incur a lock penalty. If defined, the session has not expired.
I am not referencing the session variable itself, neither reading nor
setting it. Just asking, 'Hey, are you defined?'. But maybe not. Err on
the side of safety, I suppose.
Thoughts?

I just took another look at this article myself and noticed the same thing.
While isdefined isn't covered expressly, the CF manual pages it references
at bottom both use examples that lock session and application isdefined
cfifs.

Read it many times. Great article, doesn't address this situation, IMHO.
Thanks.

Also take a look at the "ColdFusion Locking Best Practices" article by Jim

You have to lock *everywhere* including here. This is a hole in CF's CFLOCK
auto-handling, and one of many reasons to lock manually.
