Node.js is great! Run Reverse Proxy on your laptop!

Node.js is great! You can test your Hippo CMS project with a full-featured Reverse Proxy Server on your local development machine SO EASILY! This enables you to test it as same as your production server. You can download the reverse proxy script here:

By the way, this solution is very generic, agnostic to Hippo CMS, so you can apply to any different scenarios for different backends other than Hippo CMS, just by configuring the mappings in the script. See the for the details.

Hippo CMS solutions usually consist of multiple web applications and system administrators often deploy a reverse proxy server before Java application servers for many reasons. Apache HTTP Server with mod_proxy has been one of the most popular solutions for the reverse proxy node.

However, it is not so convenient to install Apache HTTP Server on a developer's computer. Sometimes they have to install compilers, make tools, etc. in order to build Apache HTTP Server!

So, I looked for an alternative solution for convenience of developers who want to test in the same environment as the production server. The solution is Node.js!
Yes, I was able to implement a full-featured, reliable reverse proxy script with Node.js very quickly.
This is my reverse proxy script project based on Node.js:

How to run the reverse proxy server script

Note: You need to install Node.js in order to run Reverse Proxy Server script.
          And, let's suppose you run the Hippo CMS 7 with Tomcat. e.g, `mvn -P` at port 8080.
  1. Follow the installation instruction in
  2. Move to the root folder of your Hippo CMS 7 project in the command line console and run the following command:

    $ sudo node rproxy.js

    The above command will run the Reverse Proxy Server at port 80 by default. (You need super user access to open port 80. That's why you need `sudo` in this example.)
    You can run it at a different port like the following example:

    $ node rproxy.js 8888
Now, if you run the rproxy.js at port 80, then visit http://localhost/ simply.

Note: Finally, DON'T FORGET to turn off '@showPort' and '@showContextPath' in /hst:hst/hst:hosts node in your Hippo Repository! If you want to run the rproxy.js at port 80 and remove the /site context path, then you must turn off those properties.
OK. Now enjoy working with rproxy.js (powered by Node.js) !!


  1. i have created a video to explain "reverse proxy" i want to share it with you to know you opinion what is reverse proxy

  2. Thanks for sharing up–to-date on this subject! Really Node.Js is best run reverse proxy

  3. Cool! Happy reverse-proxying guys! :-)

  4. You have really selected the suitable topic node.js development ; this is one of my favorite blogs.

  5. Nice !!! amazing that such a short, to-the-point list could be so useful and clear.
