User comments about offline files

This is a catch-all post for user comments and questions about offline files, aka client-side caching. I’m turning off comments on all my previous posts in the Offline Files category, and redirecting readers here instead. Hopefully this will cut down on all the duplicate answers :) As I’ve said before, don’t email me your questions – post them here instead. Wait, no, don’t post right away – first read through the comments in the previous posts! Your question has probably been answered before…
