mapfishapp - print spec does not contain the WMS version

[fvanderbiest]

By default, the mapfish print module assumes WMS = 1.1.1

If the server supports only 1.3.0, the layer is not printed (eg: the French IGN's geoportail WMS layers).

I've hacked the client side so that it sends the WMS version parameter in the print spec, but this is not enough to get the GeoPortail layers printed.

Here are the relevant mapfish-print logs:

Looks like the referer that is sent by the module is not accepted by the remote server, which expects a valid URL like http://dev.geopicardie.fr/ rather than simply dev.geopicardie.fr

Got it!
