Is the idea here that saving the data from the cookies will speedup things, because requests become smaller? Or does it have some impact on caching or something else that I am not considering right now?
I would expect that unless you have exceptionally large cookies, the saved roundtrips from another TLS handshake matter more than the data transmission for the cookies.
