How to insert headers into tilecache fetch request

[drzhouq]

@bdon I like the idea of pmtiles a lot. However, it seems that there is no easy way to incorporate some security check (via request header token)

protomaps-leaflet/src/tilecache.ts

Line 195 in 7544583

fetch(url, { signal: signal })

How would you incorporate the fetch request to pass on additional headers?

Thanks, Brandon, for your fantastic job on PMTiles.

if you are using pmtiles you can pass a custom FetchSource with your own headers:
