Nginx location, proxy_pass path/subdir missing

nginx_proxy_pass.md

NGINX location with proxy_pass

Example configuration

location /example {
  set $exampleVariable "examplePath";
  proxy_pass http://localhost:8080/$exampleVariable;
}

Example url

http://example.com/example/my/sub/dir

Expected behaviour

We expect the proxy_pass to request the uri "http://localhost:8080/$exampleVariable/my/sub/dir".

Actual behaviour

The proxy_pass uri looks like that "http://localhost:8080/$exampleVariable"

Why

Not found out so far, but based on the example above its clear, that a variable in the proxy_pass uri is causing the loss of the received location path.

Possible workarounds

1. Don't use variables in your proxy_pass
2. Update the location like that

location /example {
  set $exampleVariable "examplePath";
  rewrite ^\/example\/(.*)$ /$1 break;
  proxy_pass http://localhost:8080/$exampleVariable/$1;
}
