Needs unit tests.

This is needed to support DuckDB httpfs, which sets the Range header.

Via duckdb:

import duckdb
db = duckdb.connect(':memory:')
db.execute('install httpfs; load httpfs;')
db.execute('SELECT * FROM read_parquet("https://tiled-demo.blueskyproject.io/api/v1/node/full/bmm/raw/f8c83910-4adb-4207-a465-9ff0ff0e9cd2/primary/data/?format=application/x-parquet")')
