Hi, Have you tried with configuration option "CPL_VSIL_CURL_USE_HEAD=[YES/NO]: Defaults to YES. Controls whether to use a HEAD request when opening a remote URL."

Hi all, I am attempting to read a dataset via /vsicurl/ where I believe the server is incorrectly returning `content-length: 0` in response to HEAD requests. This causes GDAL to believe it's a zero-length file, and it therefore can't be read. If I download the file via HTTP GET, it's valid, and GDAL can read it locally. I've also confirmed I can use /vsicurl/ on some test datasets in the GDAL repo. Is it possible to force GDAL to work around the faulty content-length header, or is it too fundamental a problem to ignore? I've separately got in touch with the data provider to see if they are able to fix the issue at their end. Cheers, Daniel URL of the troublesome dataset: https://data.source.coop/earthgenome/sentinel2-temporal-mosaics/20NMH_2024-04-01_2024-08-01/B08.tif Example HTTP header responses I'm seeing: GET HTTP/2 200 date: Tue, 10 Sep 2024 13:47:54 GMT content-type: binary/octet-stream content-length: 278198294 vary: Origin, Access-Control-Request-Method, Access-Control-Request-Headers etag: "a79f3f685281d6681e4d362536c5b3eb-34" last-modified: Thu, 25 Jul 2024 13:16:08 GMT x-version: 0.0.16 access-control-allow-credentials: true HEAD HTTP/2 200 date: Tue, 10 Sep 2024 13:48:08 GMT content-type: binary/octet-stream content-length: 0 x-version: 0.0.16 access-control-allow-credentials: true etag: "a79f3f685281d6681e4d362536c5b3eb-34" last-modified: Thu, 25 Jul 2024 13:16:08 GMT vary: Origin, Access-Control-Request-Method, Access-Control-Request-Headers
