minify ...

minify Combines, minifies, and caches JavaScript and CSS files on demand to speed up page loads.

Overview

Web pages that refer to multiple CSS or JavaScript files often suffer from slower page loads, since the browser must request each referenced file individually. Most browsers will only make two simultaneous requests to a single server. The latency involved in opening multiple requests and waiting for them to finish before making new requests can result in a user-visible delay, and that can make your users sad.

Minify attempts to fix this problem by combining multiple CSS or JavaScript files into one download. By default, it also removes comments and unnecessary whitespace to decrease the amount of data that must be sent to the browser. Most importantly, it does all of this on the fly and requires only a few simple changes to your existing web pages.
