Cookie Free domains

What is the advantage of having a cookie free domain and how does one set this up on wordpress?

Advantage? It reduces unnecessary overhead and it's one of many little tweaks you can make to ensure your site is the fastest it can be.

If you have wordpress setup on www.domain.com, then all your static files (images, css, js) are served along with cookies set on the domain.

So the basic solution is the create a subdomain of your main domain (or register a whole new domain just for it) and server your static files from that domain.

I use W3 Total Cache configured to serve all static files from a subdomain which is on Amazon Cloudfront.  W3 automatically rewrites all your theme and images path to the new subdomain.  It's really easy to setup.

In addition to that, I had make tweaks to my Google analytics script to ensure it doesn't set cookies on my cookieless sub-domain.
