Nginx 利用 cookie 提供不同的版本

map $cookie_version $server {

console console;

default cdnsaas_fe;

}

upstream server1 {

server localhost:8080 weight=1 max_fails=1 fail_timeout=30s;

}

upstream server2 {

server localhost:7300 weight=1 max_fails=1 fail_timeout=30s;

}

之后使用 proxy_pass http://$server;
