Hi Stephane, I have similar requirement. I have apache (v2.2) in DMZ as reverse proxy server, port # 4244/443 were opened from QlikSense (v2.2) server inside firewall to DMZ. I was using Windows authentication method, not 'Form' method. I got 404 error message saying URL is unknown:
I am thinking to try NGINX as reverse proxy server, but notice you guys were using 'Form' method, could you explain why you decided to choose 'Form' method? Will it work with Windows authentication method?
