Of course the application can know that, that's what HTTP cache
control headers are for, the cacheability of a resource is easy to
advertise, and all browsers should know it.

really is completely silly to me and an absolute deal breaker, I
assume it's because working for yahoo you need not worry about such
things as bandwidth and cost.
