JS_CSS_DEBUG

This system variable controls whether or not CSS and JS files are combined and minified. It applies to all CSS and JS files that are registered with cssInclude and jsInclude.

If your application makes use of CSS and JS files that are not part of Andromeda, it is best to "register" them by use of the cssInclude and jsInclude functions. These functions can be put anywhere in your code. They take a relative path to the files and should never include anything like "http://" or "~/kfd/" or the domain name. A typical example would be:

<?php
jsInclude('appclib/jquery.example.js');
cssInclude('appclib/jquery.example.css');
?>

In order to provide the best performance and user experience, Andromeda outputs the necessary LINK and SCRIPT tags in the HEAD for CSS files and at the bottom of the page for SCRIPT files.

If the JS_CSS_DEBUG system variable is missing or set to N, which is the default for a server, all CSS files are combined into a single file and delivered to the browser as such, which reduces the number of HTTP calls to the server. Likewise, the JS files are combined and are also minified. This process occurs only once for each particular combination of files, and the resulting file is saved and used for all subsequent requests until it is cleared by a build.

I the JS_CSS_DEBUG system variable is set to Y, neither CSS nor JS files are combined, nor is the JS minified. This is the preferred setting when you are debugging, and is more common on development workstations.
