A simple HTTP reverse proxy written in Go.
This single-host reverse proxy listens on localhost:8080 and forwards requests to localhost:8081. Responses are stored in an in-memory cache if they include an "Expires" header. The cached responses are indexed by the request URL path.
An example "echo" server is included in cmd/origin. It allows you to control the response's Expires header based on the request's URL-encoded query string (see README.md).
This code was written for a coding challenge: write an HTTP reverse proxy with a caching feature, without using net/http/httputil. Also, this is my very first project written in Go (you have been warned!).
For a full-featured open-source reverse proxy and load balancer you should check Traefik Proxy ;)
