The hashes are used to look up objects. Even if multiple URL's are duplicated and hence their
hashes, they always point to the same object. It seems a non-easy project though. It requires
major changes to ATS.

I’m not sure I understand this, or how it helps this problem? However, isn’t this sort
of how the cache already works? There’s a hash from URL to the “header” entry, which
then has its own hash to the actual object. Alan?
