A tentative plan about NGINX Reverse Proxy ?

[Hao Lee]

Hi. I have a tentative plan about NGINX reverse proxy. I setup NodeBB on server A and setup NGINX on server B and then users access my forum.
I guess that when users request my website, HTML file is sent from A to B and then from B to user, but all other resources(images/css/js) are requested from A directly.
How about this plan. Is this right? Thanks!
