Proxy a single incomming TCP connection to multiple remote TCP servers. Only the response from one target will be proxied back to the client.
Can be used both from the command line and programmatically.
fork-proxy port [forward_host:]forward_port...
The fork-proxy command takes the following arguments:
port - The port that it should listen onforwards - a list of host:port combinations to forward TCP traffic
to. If host: is omitted, localhost is assumedThe responses from the first forward target will be piped back to the client. Responses from the remaining forward targets will be ignored.
Example:
$ fork-proxy 3000 example.com:80 example.org:80
var multi = require('fork-proxy')
// proxy TCP traffic to both example.com and example.org
var proxy = multi([
{ host: 'example.com', port: 80 },
{ host: 'example.org', port: 80 }
])
// listen for incoming TCP traffic on port 3000
proxy.listen(3000)
var proxy = multi(targets)The module exposes a single constructor function multi, which takes an
array of target TCP servers as the first argument. The array must have
at least one element.
Each element in the array must be an object. The object is passed into
net.connect()
and as such is expected to follow the same API.
The constructor function returns the proxy server which is an instance
of net.Server.
Only the response from the first target will be proxied back to the client. Responses from the remaining targets will be ignored.
Each connection object emitted on the connection event will have a
property named targets. It's an array containing the sockets created
to connect to the different target servers:
var proxy = multi([{ port: 3001 }, { port: 3002 }])
proxy.on('connection', function (c) {
console.log('connecting client to %d servers', c.targets.length)
})
proxy.listen(3000)
