redirect www request to nginx server using gitlab ce omnibus package

Dear all,

I have the Gitlab CE installed on a ubuntu machine. I have purchased a domain that directs traffic like gitlab.mydomain.com to the ubuntu server running gitlab. Now i am going to also send every request to www.mydomain.com to the same ubuntu. I would like to configure the existing nginx in the gitlab CE to forward www request to a server running debian and nginx with ip 192.168.0.241. I already modified the gitlab.rb file to include custom nginx configuration files. But now what should this configuration include so that only www traffic in http and https are forwarded correctly? so far i have this: server { server_name www.mydomain.com; location / { proxy_pass http://192.168.0.241:80; proxy_set_header Host www.mydomain.com; } } But what about https? If this works , i suppose i have to add a redirect http to https rule also?

Thx for your advice, Didier
