Hi, I've just been looking at the post below by Chris Peterson and I'm very interested in this bit in particular:
======================================================== Before: cfset request.leaky = application.leaky After: cfset request.leaky = duplicate( application.leaky ) This simple example is just an illustration of how you can get yourself into trouble when pointing a reference to objects from a shared scope like application or server, into a local scope like request. When we make a link from the request scope into the application scope, it maintains a reference such that the request variable would never go away until the referencing application variable gets garbage collected (which would wait for the application timeout). By duplicating the object into the request scope instead, this ensures there is no reference to the application scope variable, which allows it to be cleaned up after the request completes. ======================================================== If the code in index.cfm had been <cfset leaky = application.leaky> Is the same issue present? I guess what I really want to know is: 1. What is the default scope in a cfm if you don't specify a scope? 2. What is the best practice for referencing app scope cfc's from a cfm page? Many thanks, Andrew.
