Ngao (shield) - A Golang reverse proxy that limits number of client sessions connected to an upstream server.
Set a number of maximum client sessions, and the clear interval (interval in which older sessions are cleared).
Ngao is useful if you have want to rate limit access to your application/backend server, for example the configuration below only allows 20 sessions at a time.
package main
import "github.com/peteretelej/ngao"
func main() {
c := &ngao.Config{
ListenAddr: ":9015", // your listen address e.g ":9010"
Host: "etelej.com", // the backend server to reverseproxy
Scheme: "https", // protocol scheme of backend host e.g. https, http
TotalAllowed: 20, // Maximum client sessions allowed
ClearInterval: 60 * 5, // Interval to clear older sessions (secs)
}
ngao.Run(c)
