Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I'm trying to proxy several sites using nginx, and by the nature of the source I'm interested, they happen to have similar path, say /common/path. How can I get them served in different paths in my site? Say a.com/common/path goes to mysite/a-proxy/; b.com/common/path goes to mysite/b-proxy/?

I would imagine it has something to do with combination with alias and proxy_pass but not exactly sure how to deal with this. Any hint? At the bottom is my current conf file, note that a and b on the original server should have different path so that they can both be proxied in my site.

I've tried to setup sub-domain so that I can direct each of them to different server, but it seems like an overkill?

upstream a_upstream {
    server a.com;

upstream b_upstream {
    server b.com;

server {
    listen 80;
    server_name mysite.com;
    root /home/me/public_html/mysite;
    index index.html index.htm;

    location /common/path1 {
        proxy_pass http://a_upstream;

    location /common/path2 {
        proxy_pass http://b_upstream;

Your written question and code seems to be at a conflict. Are you saying that the user goes to the address: "a.com/common/path" which is then pulled from "mysite.com/a-proxy/" or are you saying a user goes to "mysite.com/a-proxy/" which then pulled from a.com? Also, setting up multiple server { ... } is the recommended way to setup virtual hosts. –  Grumpy Jan 11 '13 at 6:34
My script is not able to achieve what I want to do right now, just a reference for current setting. As you said, one solution is to set up multiple server {...} but I guess it involves subdomain setup or so on, so wondering if there is easier way to do so. –  clwen Jan 11 '13 at 14:23
I still feel that there's a gap in your question. I don't really understand what you're trying to achieve. Try editing your question to add further details or a step by step of what you expect to happen starting from user and all the way to the backend. –  Grumpy Jan 11 '13 at 16:15
