What Happens When I Cache Application.cfc Within The APPLICATION Scope?

Pretty much nothing exciting :) But I wanted to try it to see if stuff would blow up. If nothing else, it proves that a new Application.cfc instance is created for every single page request. This test is super, ultra simple. Here is my Application.cfc ColdFusion component:


	<cfset THIS.Name = "App Cache Test" />
	<cfset THIS.ApplicationTimeout = CreateTimeSpan( 0, 0, 5, 0 ) />

		Here, I am creating a unique ID for this Application.cfc
		just to help see if one instance is the same as another.
	<cfset THIS.ID = CreateUUID() />


			Param an array in the APPLICATION scope to hold all
			of our App.cfc instances.
			default="#ArrayNew( 1 )#"

			Append THIS application.cfc instance to our
			cached array.
		<cfset ArrayAppend(
			) />

		<cfreturn true />


Then, my index.cfm page merely CFDumps out the APPLICATION scope:

	Dump out the APPLICATION scope. Put in a TOP 10 to
	make sure nothing goes crazy.

After running that page a few times, here is what I get:

Application.cfc Caching In APPLICATION Scope

As you can see, nothing exciting going on here. At least it didn't go kabooom!
