A proxy server to redirect plaintext port for multiple back end servers and TLS front end for multiple backend servers
Use an npm version >= 10.16 for best results. To compartmentalize your npm, use http://nvm.sh
Run npm install to install all the dependencies
A configuration file (default: proxies.json) determines the front end to backend configuration
// To be parsed with JSON5 parser if you want to comment clearly
{
// Front end server : backend
'server1.mydomain.com' : 'https://mybackend1.local',
'server2.mydomain.com' : 'https://mybackend2.local',
'server3.mydomain.com' : 'https://external.host.com'
}
Run node ./proxy.js -h to see the options.
Once the certificates and keys are read for each of the front end servers you are securely proxying, the incoming traffic on the secure port and the plaintext port (if the plaintext redirection is turned on), will be securely proxied to configured backend servers.
