[gdal-dev] vsicurl and HTTP error 403

[Even Rouault]

Ivan,

Experimentally, I find that this particular server doesn't like HTTP requests without a
User-Agent and, more annoying, that it doesn't like Range requests used by /vsicurl/.
But as this a gzip file, seeking into it would be a inefficient process.

So the following, defining a user agent, and using /vsicurl_streaming/ that doesn't
issue range request (but require downloading everything from the beginning when
a backward seek is needed) works
gdal_translate /vsigzip//vsicurl_streaming/https://gimms.gsfc.nasa.gov/MODIS/std/GMOD09Q1/tif/NDVI/2019/249/GMOD09Q1.A2019249.08d.latlon.x33y07.6v1.NDVI.tif.gz --config GDAL_DISABLE_READDIR_ON_OPEN EMPTY_DIR --config GDAL_HTTP_USERAGENT foo

But local downloading of the file is probably a better strategy here.
