To ensure secure connections for each application, you must define SSL Options and assign them accordingly:
// (A) Reading SSL files
var fs = require('fs');
var appOneSSLOps = {
key: fs.readFileSync('./path_to_file/private.key'),
cert: fs.readFileSync('./path_to_file/certificate.crt')
}
var appTwoSSLOps = {
key: fs.readFileSync('./path_to_file/private2.key'),
cert: fs.readFileSync('./path_to_file/certificate2.crt')
}
// (B) Assigning SSL files to corresponding apps
var https = require('https');
var appOneServer = https.createServer(appOneSSLOps , appOne).listen(443);
var appTwoServer = https.createServer(appTwoSSLOps , appTwo).listen(80);
// (C) Redirecting Port 80 to 443 - > Manually or using child_process on Linux Ubuntu:
childProcess = require('child_process');
var optionExec = {timeout: 3000}; //options for childProcess.exec
childProcess.exec(
'sudo iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 443',
optionExec,
function(err, stdout, stderr) {
}
);
// (D) Enforcing HTTPS - Assuming appOne is the main application.
appOne.use(function(request, response, next) {
if(!request.secure) {
response.redirect('https://' + request.headers.host + request.url);
}
next();
});
Note: This setup assumes that appOne serves as the main application.
