Adrian will be talking about websites - how they work, get delivered to your machine and the challenges involved in caching them. He will also discuss some popular web applications, including Youtube and Google Maps, and present the challenges involved in caching these in a way that is transparent to the end user.

Adrian Chadd runs a consulting and hosting business, specialising in Squid and Xen hosting. He also develops for Squid, the open-source HTTP caching proxy project.
