The metadata mention seems very fuzzy. I am not saying you did something
wrong, but at least that seems very fixable if you know what is going on.
The mirror issues seems evident and inherent to the solution. Although I
would not be surprised if there was a smart fix for linking different
location with the same content to avoid cache pollution.

Then tell us what a real solution looks like ? I am confident that writing
a simple proxy server that does exactly what you want cannot be hard to
write yourself.
