[gdal-dev] How to access remote data that requires authentication?

[Even Rouault]

The mention to _netrc is weird...

Regarding authentication issues, this service is quite annoying and 
requires enabling cookies. See 
https://lists.osgeo.org/pipermail/gdal-dev/2021-October/054728.html

You need to add things like /--config GDAL_HTTP_COOKIEFILE 
/tmp/cookies.txt --config//GDAL_HTTP_COOKIEJAR /tmp/cookies.txt/
