I used nginx and upstream module for load balancing with the following config

upstream lb {
  server 127.0.0.1:8080;
  server 127.0.0.1:8081;
 }
 server {
  listen 88;
  server_name localhost;

  location /cas/ {
    proxy_pass              http://lb;
    proxy_redirect          off;
    proxy_connect_timeout   2;
    proxy_set_header        Host            $host;
    proxy_set_header        X-Real-IP       $remote_addr;
    proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
  }
}

the problem is the "location /context/" have to match to the context of backend server so when i request localhost/context/index.html then nginx routes it to 127.0.0.1:8080/context/index.html or 127.0.0.1:8080/context/index.html.

Is it possible to have difference backend context and nginx location for example with "location /" nginx will routes the request to 127.0.0.1:8080/context/index.html or 127.0.0.1:8080/context/index.html

Thank you.

I'm using nginx and NginxHttpUpstreamModule for loadbalancing. My config is very simple:

upstream lb {
    server 127.0.0.1:8081;
    server 127.0.0.1:8082;
}

server {
    listen  89;
    server_name localhost;

    location / {
            proxy_pass      http://lb;
            proxy_redirect  off;
            proxy_set_header        Host            $host;
            proxy_set_header        X-Real-IP       $remote_addr;
            proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

But with this config, when one of 2 backend server is down, nginx still routes request to it and it results in timeout half of the time :(

Is there any solution to make nginx to automatically route the request to another server when it detects a downed server.

Thank you.
