How to preserve request url with nginx proxy_pass
Just proxy_set_header Host $host miss port for my case. Solved by:
location / { proxy_pass http://BACKENDIP/; include /etc/nginx/proxy.conf; }and then in the proxy.conf
proxy_redirect off; proxy_set_header Host $host:$server_port; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
Note to other people finding this: The heart of the solution to make nginx not manipulate the URL, is to remove the slash at the end of the Copy: proxy_pass directive. http://my_app_upstream vs http://my_app_upstream/ – Hugo Josefson
I found this above in the comments but I think it really should be an answer.
