Minify – Combine & Compress CSS or Javascript Files
Minify is a PHP5 app that can combine multiple CSS or Javascript files, compress their contents (i.e. removal of unnecessary whitespace/comments), and serve the results with HTTP encoding (gzip/deflate) and headers that allow optimal client-side caching.
Yahoo’s Combo Handler and Google’s AJAX Libraries API both serve content from their heavy-duty CDNs and potentially increase the chance that your visitor will already have a file in her browser cache. Neither service serves custom content that you provide. You may wish to use these services to serve popular libraries and Minify to serve your code.
