Actually, from the browser it would send a GET request which is not the
one sent by geonode. But if I use cURL:
curl -v -u xxx:xxx -X POST
"http://geonode.aua-toulouse.org/geoserver/rest/printng/render.png?width=240&auth=xxxxxx&height=180"
I receive the same 405 error.

Yes, I've noticed that. I normally receive a 500 error with a "wrong
response : " message, because of the image file being empty. But if I
change geoserver/helpers.py to return the server response instead of the
server content (which shloud be the image but is empty), I can see in
firebug that geoserver actually responded with a 405 error.

Best regards

Guillaume
