Right. This is what Allaire recommends in "ColdFusion Best Practices"
<cfquery name="variables.qUser" datasource="#request.dsn#">
SELECT FirstName, LastName
FROM Users
WHERE UserID = #request.UserID#
</cfquery>
<cflock scope="application" timeout="2" type="exclusive">
<cfset application.qUser = variables.qUser>
</cflock>
at http://www.allaire.com/handlers/index.cfm?id=17318&method=full
But for Structures, this was thrashed out recently in the Fusebox list. I
thought the consensus there was not to bother with the additional step of
copying the structures, and use something like the following in
qry_globals.cfm or Application.cfm:
<cflock scope="Application" type="ReadOnly" ...>
<CFSET Init = (NOT isDefined("Application.MyStruct") OR Not
isStruct(Application.MyStruct))>
</cflock>
<CFIF Init>
<cflock scope="Application" type="exclusive" ...>
<CFSET Application.MyStruct = StructNew()>
...read data here into Application.MyStruct for some
time....
</cflock>
</CFIF>

I don't know about Paul, but I generally build structures in local
scope<br>
and then copy them to application (or session) scope with a single
cflock<br>
for the copy, instead of locking the entire process. Particularly
if I'm<br>
initializing a bunch of structures, I'll build them all and copy them
all<br>
under one cflock.<br>
