IPv4 header to requests when a client is using IPv6

  What is Pseudo IPv4? As a stopgap to accelerate the adoption of IPv6, Cloudflare offers Pseudo IPv4 which supports IPv6 addresses in legacy applications expecting IPv4 addresses.

Let's say you have a file on your server   http://www.domain.com/Portals/0/scripts/CoolStyles.CSS a trace route can show you the steps that it takes a particular user, on their internet connection to request that file from your server. When a request for a specific file is made by a user, the server closest to that user (in terms of the minimum number of nodes between the server and the user) is dynamically determined. This optimizes the speed with which the content is delivered to that user. When on a CDN, the steps are reduced because (hopefully) they are closer to your location, AND they're serving a cached copy of your file so that the request load is not on your server.   http://Geographically Locat...
