Correct proxy path in nginx.conf

Question

we have two servers, A and B. Server A is accessed worldwide. He has nginx installed. That\'s what I have in conf:

location /test {
  proxy_pass http://local         


        

Answer 1

That should work. Nginx should strip the '/test' path on the upstream local server. So what I can say is that is not the cause. To make it a bit better, try this:

location /test/ {
  proxy_pass http://localserver.com/;
}

The 2 slashes I added at the first 2 lines will avoid mistakenly match '/testABC' and send the wrong request to the upstream local server, for example.

Do you have a

proxy_redirect

line in the same location block? If your upstream local server has redirects, then a mistake on that line will cause an issue like you described.

[UPDATE] Found the root cause why the original config didn't work and mine works: nginx does NOT replace URI path part if the proxy_pass directive does not have a URI path itself. So my fix of adding a slash (slash is treated as a URI path) at the end triggers the URI path replacement.

Reference: http://wiki.nginx.org/HttpProxyModule#proxy_pass

If it is necessary to transmit URI in the unprocessed form then directive proxy_pass should be used without URI part

location  /some/path/ {
  proxy_pass   http://127.0.0.1;
}
