This is collection of essays written by me, Morten Fangel. My hope is that these essays inspire you to create a better solution than the one I outline. I've tried to keep examples small and generic enough to allow for easy extension of the solutions described in my essays.

An outline on how to get Varnish to detect if the user is using a mobile device to access your site and how to have a cache group for each device type. I will also talk about how you can then get Drupal to serve your site with a mobile friendly theme when Varnish detected a mobile device.
