Barney,
The docs state that you can call the onStartApplication event,
"If you call this method explicitly, ColdFusion does not start the
application; it does execute the method code, but does not lock the
Application scope while the method executes."
What does that leave us with as a "best practice" for reinitalizing
application scoped cfc's during development. I'm wondering about
adding a method to application.cfc immediately under
onApplicationStart, say restartApp, include the same createObject
calls, but lock them. I'm hoping i can add something like
if (StructKeyDefined(url, "restart")) {
restartApp();
}
in onRequestStart - not 100% sure if url scoped variables are
available to onRequestStart tho'. Have to give that a try.
Mike, if you haven't already, i'd read the livedocs about
Application.cfc in the Developer's guide. Look under Designing and
Optimizing a ColdFusion Application. The section on Application.cfc is
particularly good.
I know what you mean about the high level overview tho'. It really
helps to get an detailed overview before you dive into "Now what would
be useful to implement here ..." I was at a presentation by Ben Forta
about CFMX 7 and it was very good for just that. I'd suggest looking
for a breeze presentation online by him on CFMX 7 - i think there's
one available.
