Right. I think we have three orthogonal issues on this thread:
We would like an indication of whether or not an object came from HTTP cache —> Ilya’s proposal to use “age” is on the table.
We would like an indication of whether or not a preloaded resource was used: https://github.com/igrigorik/resource-hints/issues/19.
We want to know the size of a resource either including HTTP headers or just the attachment or both.
