Hi,
I have a conf with two virtual hosts and a proxy-pass that is dependent on which host the request arrived to, like this:

server {
listen 80;
server_name x.com y.com;
resolver 8.8.8.8;
root /var/www/html;

location / {
# whatever
}

location /api/ {
proxy_pass http://api.$host/;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $host;
}
}

Note the trailing "/" on proxy_pass which should forward the uri untouched, stripping out "/api". However, the uri is not forwarded at all, e.g. GET http://x.com/api/somehing is forwarded to api.x.com without the "/something" part.
But, if I hard code the proxy_pass url, like this:
proxy_pass http://api.x.com/;
it works, the uri is properly forwarded.

Doesn't proxy_pass have proper support for variables or have I done something wrong?

Many thanks / Jonas
