[Zope] Download counter - only successful downloads

[Danny William Adair]

I would also like to implement a download counter.
Is there any realistic way of having it count only files that have been 
_successfully_ and _fully_ downloaded? I know there is a "precondition" for 
file objects (that can do whatever, e.g. increase a counter), but is there 
something like a postcondition?

I am not sure if this is actually possible, but my feeling is yes.

Thanks for your help,
Danny
