MBTiles download endpoints do not respond to HEAD requests.
Looked into this briefly, it looks like something is intercepting these requests before it hits the download route (I tried adding a use middleware and could not log HEAD requests). Requires further study.
Out of curiosity, what is concretely affected by not being able to make HEAD requests here?
The iPad app will be affected here. I am seeing this periodically, with a HTTP 502 from CloudFront on certain files. The iPad app uses HEAD requests to determine download size so that progress can be shown when downloading MBTiles in the app.
