[gdal-dev] Hi: GDAL CONFIG

[Michał Kowalczuk]

Thank you Jukka, it helps in command line.
Now I need to investigate why the same but using C API fails.
The issue scenario is:

   1. I set *GDAL_HTTP_USERPWD* using *CPLSetConfigOption*
   2. I connect to the service as dataset (*GDALOpen*)
   3. I get the first subdataset (*GDALOpen*) and download data using
   *GdalRasterIO*
   4. I connect to the second subdataset and when I got handle to it,
*GDAL_HTTP_USERPWD
   env variable is cleared!*
   5. So GdalRasterIO fails because of lack the credentials...

Strange... 🤷
