You've got it correct. An instance of a cfc created on a page is no
different than any other variable created on a page - it's gone when you
leave the page.
Where it gets murky with CFC's is whether or not you're creating it with
createObject or using cfinvoke to just hit a method that doesn't return an
instance of the object. So, for instance this would work:
<cfset myObj = createObject("component", "myComponent")>
<cfoutput>
#myObj.sayHello()#
</cfoutput>
And, this would work:
<cfinvoke
component="myComponent"
method="sayHello"
returnVariable="hello">
</cfinvoke>
<cfoutput>#hello#</cfoutput
But, the first one creates an object (myObj) that can be re-used
throughout your page. So, you could also do,
<cfoutput>#myObj.sayGoodbye()#</cfoutput> without
re-instantiating the object. The second does not keep a reference to
the object for further use.
