Reverse Proxy - NGINX Reverse Proxy

When NGINX proxies a request, it:

Passing Request Headers

Pass to a domain

To pass a request to an HTTP proxied server, the proxy_pass directive is specified inside a location. 

location /some/path/ {
    proxy_pass http://www.example.com/link/;
}

NOTE: The address of the proxied server is followed by a URI, /link/.

  • If the URI is specified along with the address, it replaces the part of the request URI that matches the location parameter.
  • For example, the request with the /some/path/page.html URI will be proxied to http://www.example.com/link/page.html.
  • However, if the address is specified without a URI, or it is not possible to determine the part of URI to be replaced, the full request URI is passed (possibly, modified).

Proxy to an IP Address (and optional port)

location ~ \.php {
    proxy_pass http://127.0.0.1:8000;
}
