I presented this morning at RailsConf about Edge Caching and ESI. You can download my presentation below.
Assembling Pages Last: Edge Caching, ESI, and Rails
People asked some awesome questions, caught the edge cases I didnt want to cover which were complicated, like authorization/security, multi-level ESI includes, per page include limits, etc. The people at RailsConf are awesome. Thats totally why I enjoy these events.
