HTTP Demuxer

Configurable HTTP traffic forwarder written in Go.

This application works as HTTP reverse proxy. It aggregates traffic from several sub/domains and forwards it to specified host and port. Main purpose is to route traffic to different services running on the same server.

Configuration

Routing is based on the rules specified in JSON file:

{
    "port": 80,

    "forwards": {
        "www.example.com": ":8000",
        "blog.example.com": ":8001",
        "service.example.com": ":8002"
    },

    "redirects": {
        "example.com": "www.example.com"
    }
}

With this config, demuxer will listen on port 80 and forward all requests to www.example.com to local port 8000, blog.example.com to 8001, and service.example.com to 8002. It will also redirect all requests to example.com to www.example.com.

If demuxer receives request not specified by any forward or redirect, it returns 404 Not Found error.

Usage

./http-demuxer routes.json
