| Ahh, but that _is_ a cache ... a manually maintained one.

Yes, I realize that.

I know that, too :-)

In practice, I don't think maintaining a catalog file is a headache at
all. I suppose a proxy would be more transparent in some ways, but
I think installing and maintaining one would be quite tricky for most
people.

For one thing, a simple LIFO proxy isn't sufficient. You'd need to be
able to tailor it in some way so that different classes of entries
never expire from the cache.

And I don't oppose a broader solution. :-)
