No. Location: is not used in that way. Location: is used when a object
is moved to a new location (redirect), and similar situations.

You are thinking on Content-Location, but by security reasons it is not
useful in this context ("correcting" the server part of a URL). It Squid
used this header, then anyone could set up a server that injects a fake
home page into a Squid cache.

By security reasons cache key (URL) needs to be from the actual request,
and possibly some variables from the response added to that (not done at
the moment).
