How to send CSS to the client using HTTP response headers?

Your question is not very descriptive, but you are probably refering to this article which was recently posted online.

It really is not that hard: RFC5988 describes the LINK header, which allows you to send <link> elements through HTTP headers instead of including them in the HTML.

Like the example in the article, usage is similiar to this:

Link: <some-document.html>;rel=prefetch

...which would have the same effect as placing this in your HTML:

<link href="some-document.html" rel="prefetch"

When using a language like PHP, you would have to write a line of code similiar to this:

<?php header('Link: <demo.css>;rel=stylesheet'); 

PLEASE NOTE: only FireFox and Opera seem to support this header at the time of writing.
