gogo-proxy

A fast and robust http/websocket reverse proxy library written in Go

Features

• Simple:
  • Implements http.Handler interface
  • Easy to write Balancers for custom routing logic
  • Built-in balancing patterns (Roundrobin, Random, etc ...)
• Robust: Retry requests on failure
• Flexible:
  • Custom error handling (so you can draw custom error pages etc ...) (use ErrorHandler)
  • Custom request rewriting (use Rewriter)
  • Your Balancer lookups can use information from the request, hard coded rules or they can query databases such as redis, memcache, etcd, mysql, ...
• Fast & "scalable":
  • Written in go, so concurrent by default and fast
  • Easy to deploy (proxies can be compiled as single binaries)

Example

package main

import (
    "github.com/AaronO/gogo-proxy"
    "net/http"
)

func main() {
    p, _ := proxy.New(proxy.ProxyOptions{
        Balancer: func(req *http.Request) (string, error) {
            return "https://www.google.com", nil
        },
    })

    http.ListenAndServe(":8080", p)
}
