What happens if you copy structures into the request scope? AFAIK a
structure copy like 'Request.s = Application.s' only copies a pointer to
the structure. Isn't there a problem when one template reads
Request.s.foo, while another template sets or modifies Application.s.foo?
That's why you use the Duplicate() function. It creates a real copy, not a
pointer. If you don't have CF 4.5.1, then you must use StructCopy(), but be
aware that StructCopy() has a bug. If Application has a key that's a
structure itself, then when you structcopy it, every 'first' level key will
be really copied, but the second level structure will create a pointer.
Example:
<CFSET A = StructNew()>
<CFSET A.Name = "Ray">
<CFSET A.Lower = StructNew()>
<CFSET B = StructCopy(A)>
At this point, if I do:
<CFSET B.Name = "CCC">
It will NOT change A.Name.
But, if I do this:
<CFSET B.Lower.Foo = "ddd">
it WILL set A.Lower.Foo.
So, if you have CF 4.01, you must keep your App scope 'one level deep',
that's if you want to use the 'copy to request' trick.
