I thought application.cfm is read every time there is a request to the CF
server? Why would anyone set an application scope in the application.cfm
file? Application scopes have nothing to do with application.cfm? Right?
I just finished Advanced CF Development a couple of weeks ago and Bruce Van
Horn, our instructor, said it was good practice to lock ALL application,
session and server scope variables. Either you lock them all or don't bother
with any.
A little confused,

Subject: Locked App Scope vs. Request Scope
I have followed the various threads on locking Application scope
variables and on the use of the Request scope, but I still have a
question.
I create and populate an Application-scope structure in Application.cfm.
This is done only once, when the application is first initialized. I use
this structure on many pages, within a readonly lock.
I know that I could copy (via Duplicate) the structure into the Request
scope and omit the lock.
Which method is better? For what regime does Duplicate beat CFLOCK? I
imagine this would be a function of the structure's complexity and of the
number of CFLOCK calls.
(A variation of the Request scope method would be to create/populate the
structure directly in the Request scope, eliminating usage of the
Application scope. But it seems to me that this would be slower than
simply copying it from the Application scope into the Request scope.)
Thanks.
