Description

В переменной $sticky_backend находится значение "def_backend". Upstream с таким именем существует:

    upstream def_backend {
        server 127.0.0.1;
    }

При попытке использовать $sticky_backend в proxy_pass вот так:

            proxy_pass http://$sticky_backend:8080;

я получаю ошибку:

2013/07/31 11:52:07 [error] 58044#0: *1 no resolver defined to resolve def_backend, client: 88.103.18.63, server: dsh.perceptyx.com, request: "GET /demox/ HTTP/1.1", host: "dsh.perceptyx.com"

Хотя upstream с именем def_backend и существует, но вот upstream-a с именем def_backend:8080 - нет.

Правильная конфигурация выглядит как-то так:

upstream def_backend {
    server 127.0.0.1:8080;
}

proxy_pass http://$sticky_backend;
