[REBOL] Re: read-thru check refinement

Thanks Larry. Yes, that works, though I was sure I'd tried it.
Still, it doesn't explain why we have to supply the date and time
since they must be with the already downloaded file, right? And
what's the point of supplying a logic or none?
All very confusing... (:
