Duplicate() is used with CFSET to copy a complex variable (query, array or structure).
If you don't use Duplicate() then the copy is not a real copy, but a pointer back to
the original - this can cause problems with shared-scope variables (application,
session, server).

Someone correct me if I'm wrong but I believe the best way to copy is

sometimes a problem when you have nested structures and those nested
structures don't get copied or may be corrupted when you use
structcopy(). I'm not sure if
Are these two the same? If not, what is the difference between
