If you are just using FileUpload "out of the box" (i.e. without adding your
own custom classes), I wouldn't bother trying to cache instances of the
FileUpload classes. The instantiation cost is insignificant. You'd be better
off spending your time optimising the threshold between memory and disk
storage for your particular scenario.
