    mode http

    bind *:8080

backend be1
    nuster cache on
    nuster rule img ttl 1d if { path_beg /img/ }
    nuster rule api ttl 30s if { path /api/some/api }
    server s1 127.0.0.1:8081
    server s2 127.0.0.1:8082

There are four basic sections: global, defaults, frontend and backend.

  • global
    • defines process-wide and often OS-specific parameters
    • nuster cache on or nuster nosql on must be declared in this section in order to use cache or nosql functionality
  • defaults
    • defines default parameters for all other frontend, backend sections
    • and can be overwritten in specific frontend or backend section
  • frontend
    • describes a set of listening sockets accepting client connections
  • bankend
    • describes a set of servers to which the proxy will connect to forward incoming connections
    • nuster cache on or nuster nosql on must be declared in this section
    • nuster rule must be declared here

You can define multiple frontend or backend sections.
