If the server won't tell you the size of the object, then the only other 
thing you can do is download the object yourself and compute its size - 
there's nothing else you can do.

The size is often not reported if the content is being generated on the 
fly. Anyway, maybe there's another way to solve the problem you're 
working on - why do you need to know the sizes?
