Nginx: How to forward an HTTP request to another port

nginx

What I want to do is: When someone visits http://localhost/route/abc the server responds exactly the same as http://localhost:9000/abc

Now I configure my Nginx server like this:

location /route {
    proxy_pass  http://127.0.0.1:9000;
}

The HTTP request is dispatched to port 9000 correctly, but the path it receives is http://localhost:9000/route/abc not http://localhost:9000/abc.

Any suggestions?

I hate the subtlety here, but try adding a / at the end of 9000 like below. It will no longer append "route" to the forwarded request now.

location /route {
    proxy_pass  http://127.0.0.1:9000/;
}

Turn out my first answer to this question was correct at certain time, but it turned into another pitfall - to stay up to date please check Taxing rewrite pitfalls

I have been corrected by many SE users, so the credit goes to them, but more importantly, here is the correct code:

server {
       listen         80;
       server_name    my.domain.com;
       return         301 https://$server_name$request_uri;
}

server {
       listen         443 ssl;
       server_name    my.domain.com;
       # add Strict-Transport-Security to prevent man in the middle attacks
       add_header Strict-Transport-Security "max-age=31536000" always; 

       [....]
}

NGINX – Proxy HTTPS Requests to an HTTP Backend

The type of proxy you are trying to set up is called a reverse proxy. A quick search for reverse proxy nginx got me this page:

In addition to adding some useful features like an X-Forwarded-For header (which will give your app visibility into the actual source IP), it specifically does:

proxy_redirect off

Good luck! :)
