In reproducible: Enhance Reproducibility of R Code
.probeRange R Documentation
Probe a URL for size and HTTP Range support

Internal helper for the parallel ranged download path. Sends a HEAD request
and reads Content-Length and Accept-Ranges. Any failure (HEAD not
supported, timeout, httr2 unavailable) returns size = NA /
acceptRanges = FALSE, which the caller treats as "use single-stream".
Usage
.probeRange(url, verbose = getOption("reproducible.verbose", 1))
Arguments
url
The URL to probe.
verbose
Numeric verbosity level.
Value
A list with size (numeric, bytes or NA) and acceptRanges
(logical).
