References for anyone interested: "a rough note on how the browsers Firefox and Chrome implement caching" (https://github.com/c42/wrest/blob/master/Caching.markdown#a-rough-note-on-how-the-browsers-firefox-and-chrome-implement-caching)

This was written a few years back and the source code referenced there would've changed, but at that time I had dug into actual browser implementations to figure out the caching logic, as well as mnot's canonical guides about caching. (https://www.mnot.net/cache_docs/)
