[gdal-dev] netcdf url : should lack of range support be the error?

[Michael Sumner]

on this URL I get an error, and as far as i understand - the server doesn't
support range downloading, the file otherwise works fine.

gdalinfo failed - unable to open '/vsicurl/
https://erddap.emodnet.eu/erddap/files/biology_6640_benthos_NorthSea_e4af_0f0e_6a73/04_2021_6640_diva_benthos_erddap.nc
'.


Should this trigger "Range downloading is not supported by this server" ?

Full output with debug messages on:
