This is the home page of the mirroring activity of the W3C Systems Team . This activity is the continuation of the W3C-LA Mirroring Activity . This page describes the nature and the objectives of the W3C mirroring system in a non-technical way. The aim of this activity is to spread mirrors of the W3C site around the world. This is not a research topic in order to find a general way to make web mirrors, but a specific development issue taking advantage of all particularities of the W3C web site.
All mirrors are, to a certain extent, linked, and get or give services from or to other mirrors.
In this organisation, there are no master servers and no slaves, but only a set of machines serving the same content. However, all mirrors are independent in that they can continue serving information even if they are not in contact with each other. The mirroring policy is completly hidden for our customers, and a unique URL will always reach the closest mirror. According to who is hosting a mirror, only authorized information will be stored on the hosted mirror. However, all requests arriving on a given mirror are served either locally or delegated to another mirror.
