Excuse me for the mail that was not clear, I don't find the correct technical term to use.

Yes "market.cloud.com" and "panel.cloud.com" resolve to the nginx server.

When I do "curl -i http://panel.cloud.com/", Iget the response from 10.1.0.16 and it work fine because it's on the location /

When I do "curl -i http://panel.cloud.com/panel", I get the response from 10.1.0.12 but with /panel on the URL. So After i get the home page I can't go the the other page because the URL contain the "/panel"

My issue is to point the nginx server to many backend server, the nginx requires to have different location which cause probleme to navigate in the different backen server. Is there a solution to work with nginx as a reverse proxy for many backend servers (differents sites)

Thank you in advance
