A possible solution could be for apt to look at the Last-Modified
timestamp reported by the HTTP server for the Release file, and issue
the HTTP requests for Packages.gz and Sources.gz with Cache-Control:
max-age=x, where x is the current time minus Last-Modified.
There's already an Acquire::http::Max-Age option, so it should be a
matter of using a different default value for that for Packages.gz and
Sources.gz. If it still goes wrong, you can set Acquire::http::No-Cache
