"Fastly-Debug:1" looks useful (if only I could understand what the
gobbledegook it produces was... :)).

A very recent try shows the cache still serving up very old files for
`latest':

```
$ curl -I https://nycdn.netbsd.org/pub/NetBSD-daily/HEAD/latest/amd64/binary/sets/kern-GENERIC.tar.xz

as opposed to getting it via the directory itself:

```
$ curl -I https://nycdn.netbsd.org/pub/NetBSD-daily/HEAD/202208070110Z/amd64/binary/sets/kern-GENERIC.tar.xz
