Detailed procedure how to build your own cost-effective CDN

Sigh... It all feels so exaggerated, except perhaps for the most humongous of media conglomerates or multinationals. For instance:

> Speed for local visitors — all browsers have a limit on the maximum number of concurrent requests per server IP address. If the browser can load content from multiple different domains and IP addresses (domain sharding), it will allow more parallelization and the content will load into the browser faster.

Or just write sensible fricking Web pages to begin with, then you don't need any damn "CDN". How many connections does a browser need, to download a few KB of HTML and a handful of pictures?

I thought the Internet was the content distribution network. If your shit doesn't work on that, rethink your shit.
