Apache / mod_perl and nginx

Apache 2 + mod_perl serve the dynamically generated HTML pages from Product Opener.

nginx is installed on port 80 as a reverse proxy. It serves the static files (images, JS, CSS etc.) and proxies the dynamic requests to the Apache server on another port.

apt-get install apache2

1. stop apache in order to be able to install nginx (default port 80)

service stop apache2

apt-get install nginx
