I forgot to mention something:

HTTP: request failed with curl error code 7 (Failed connect to
agropilot:80; Operation now in progress) for
http://myserver/sld/polygon_simplepolygon.sld

It may be obvious, buy "myserver" is really "agropilot", an url from
my internal network. I replaced "agropilot" for "myserver" to simplfy
it (I forgot to replace it one time, sorry). The point is the url
http://agropilot/sld/polygon_simplepolygon.sld is reachable in my
network. I can see the file using a web browser, but curl fails. I
don't know why.
