-====== Setting Up Node.js ======
-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.
-The following wiki guides you through the steps to set up Node.js with LiteSpeed Web Server. The wiki assumes that you have a functional LSWS installation running off of Apache configurations (though the steps can be easily adapted to using LSWS native configuration files).
-===== Install Node.js =====
-Get the latest Node.js package.
-  wget http://nodejs.org/dist/node-latest.tar.gz
-Expand the tarball.
-  tar xvzf node-latest.tar.gz
-Build Node.js from the tarball.
-  cd node-vX.X.X
-  ./configure
-  make
-  make install
-===== Proxy Node.js Traffic =====
-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:
-  RewriteEngine On
-  RewriteCond %{REQUEST_FILENAME} !-f
-  RewriteCond %{REQUEST_FILENAME} !-d
-  RewriteRule ^(.*)$ http://ghost.domain.com:XXXXX/ghost/$1 [P,L]
-The above example redirects all traffic (after checking that it is a directory or file) to a Ghost subdomain using port XXXXX. Port XXXXX should be the port Node.js is running on.
-==== If Using LSWS Below 4.2.13 or Proxying to an External Server ====
-In order for LSWS to proxy traffic to another web server, LSWS needs a proxy-type external application. Starting with LSWS 4.2.13, LSWS will automatically create a proxy external application for rewrite rules that redirect to a local web server. If you are using a version below 4.2.13 or are running Node.js on a different server, you will need to use the following steps to manually create a proxy external application to proxy to Node.js in addition to adding the rewrite rules above.
-=== Create a Web Server External Application ===
-Add a new external application (WebAdmin console > Configuration > Server > External App > Add). Choose "Web Server" as the Type.

-=== Configure the Web Server External Application ===
-{{litespeed_wiki:create_proxy_extapp.png?700}}
-In the above configurations we have made the Location 1.2.3.4:50000. It is important that the Location match the IP (127.0.0.1 if it is on the same server) and port Node.js is running on.
-After saving the configurations, restart LSWS to save changes. Your traffic should be redirected to Node.js now.
-===== Notes =====
-  * If you encounter errors using Node.js, please make sure that Node.js is started and running when using it.
