 Node.js is a platform that generally runs as a separate web server. LiteSpeed Web Server can be configured to proxy traffic to Node.js so that users can run Node.js applications (like Ghost) on their sites. Node.js is a platform that generally runs as a separate web server.

 +For the rest of this wiki, we will be using the example Node.js web server ''​example.js''​ found on [[http://​nodejs.org/​|Node.js'​s homepage]]. This web server runs on port 1337 and responds with "Hello World" to every request.

-Now that Node.js is installed on your server, you will need to tell LSWS to send the proper traffic to Node.js. Starting with LSWS 4.2.13, this can be done with a just a rewrite rule (if Node.js is installed on the same server as LSWS). Simply add a rewrite rule that will redirect traffic to the port Node.js is listening on. The following is an example:+Now that Node.js is installed on your server, you will need to tell LSWS to send the proper traffic to your Node.js ​application.

Simply add a rewrite rule that will redirect traffic to the port Node.js is listening on. The following is an example, the domain name for the site is "​example.com",​ Node.js application server is running on port 1337, add the following rewrite rule to .htaccess under document root directory. ​

Port XXXXX should be the port Node.js is running ​on.+The above example redirects all traffic (after checking that it is a directory or file) to port 1337 (where ''​example.js'' ​is running, as noted above). Static files are still served by LSWS.
