[gdal-dev] /vsicurl, curl and wget

[Javier Jimenez Shaw]

What I don't understand is why it works with wget but not with curl
(independently of GDAL). I tried it in my Ubuntu and it happens as well.
There is probably something "picky" in that server, but what? I tried with
a different user agent, but no change.

If you find out the reason, please tell us.
