Proxy Middleware

Proxy provides an HTTP/WebSocket reverse proxy middleware. It forwards a request to upstream server using a configured load balancing technique.

Usage

url1, err := url.Parse("http://localhost:8081")
if err != nil {
  e.Logger.Fatal(err)
}
url2, err := url.Parse("http://localhost:8082")
if err != nil {
  e.Logger.Fatal(err)
}
e.Use(middleware.Proxy(&middleware.RoundRobinBalancer{
  Targets: []*middleware.ProxyTarget{
    &middleware.ProxyTarget{
      URL: url1,
    },
    &middleware.ProxyTarget{
      URL: url2,
    },
  },
}))

e := echo.New()
e.Use(middleware.ProxyWithConfig(middleware.ProxyConfig{}))
