[gdal-dev] accessing netCDF files with /vsicurl fails

[Joaquim Luis]

Hi,

This type of command used to work before, but it now errors  (fresh Win7 
64 GDAL)

gdalinfo /vsicurl/ftp://topex.ucsd.edu/pub/srtm30_plus/srtm30/grd/w020n40.nc

ERROR 4: 
`/vsicurl/ftp://topex.ucsd.edu/pub/srtm30_plus/srtm30/grd/w020n40.nc' 
not recognised as a supported file format.
gdalinfo failed - unable to open 
'/vsicurl/ftp://topex.ucsd.edu/pub/srtm30_plus/srtm30/grd/w020n40.nc'.


and if I try with a closer site it still errors but prints quite some 
more info
