as ray points out, in "principle", structcopy should be faster. by what margin, i don't know. but the principle remains.

It's only necessary to use Duplicate in this case if Session.var is a structure or a query. If it's just a simple value, you don't need to worry - simple values are always passed by value, not by reference.
