[Qgis-user] Problems with Qgis Server 2.12

Fri Nov 20 09:12:14 PST 2015

Hi all

A quick answer to ask for incorporating the environment variables in the
documentation
https://github.com/qgis/QGIS-Documentation/blob/master/source/docs/user_manual/working_with_ogc/ogc_server_support.rst

If no one is available, I will do this next monday.

Regards,
Michaël
