loadbalancing with difference nginx location context and backend server context

Question

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.

You can have multiple location statements each with it's own upstream

location /cas/ { proxy_pass http://lb; } location /web/ { proxy_pass http://2b; } location /mail/ { proxy_pass http://3b; } 

You can also use if statements that checks the $request_uri variable and uses that to decide what upstream to pass the request to.

if ($request_uri ~* "^/(.+?)/context") { proxy_pass http://domain.com$request_uri; break; }
