http reverse proxy for personal use

WeeProxy

WeeProxy is a wee bit http proxy to access http services mapped over URL path.

• HTTP Proxy based on URL path mapped to Backends

• round-robin load-balancing

• graceful stop/restart

• prometheus performance metrics at /metrics

• configurable header customization

• rate-limiting (same config for all backends)

• circuit breaker (same config for all backends)

Quikstart

• start server

dep ensure

go run weeproxy.go

• can also be used by downloaded pre-compiled binary from latest release, remember to have sample config in same dir or set required env var

• check http

curl localhost:8080/nothing

curl localhost:8080/google

Config

• config to be used can be changed by providing path to env var WEEPROXY_CONFIG

• proxies based on URL Path maps provided as configuration like, sample config

{
  "server": {
    "listen-at": ":8080"
  },
  "url-proxy": {
    "/google": "http://www.google.com http://www.google.in",
   ....more
  },
  "custom-headers": {
    "X-Proxy-By": "WeeProxy"        // custom response headers for each response
  },
  "sanity": {
    "max-errors-per-sec": "10",     // per backend max errors allowed before ban
    "max-request-per-sec": "7000"   // per backend max requests allowed before ban
   }
}

in sample config above, when multiple backends need be load-balanced they are separated by a space

if any other character gets used as separator, env WEEPROXY_LB_SEPARATOR need be set with same

• port to listen at can be modified updating listen-at field in above config

---

ToDo

• better no-backend handling

• runtime authenticated config updates over admin api

• rate-limiting (per backend config)

• circuit breaker (per backend config)
