You're best bet would be to put a proxy cache in front of Zope. Zope's no=
t=20
very efficient at serving big static files like this compared to Apache o=
r=20
squid.

I think it would be nice to be able to control cacheability of certain=20
objects. However it smells like a YAGNI, especially with good front end=20
caches that can take care of it.
