But such an attack would only need the cookie sent once client-to-server. A GET request which sends the secret cookie would work just fine. If there happened to be additional request(s) over that channel transmit the adaptive plaintext (constructed from the ciphertext block containing secret cookie data), would it actually be a requirement that they re-send the cookie then? Even if there were CSRF restrictions on cookies, would they apply to GET and POST equally? If cookie restrictions applied to GET, how would https://google-analytics.com/ work? Sorry if I sound nonsensically hypothetical. I'm still trying to figure out what I've promised not to say vs. what I already knew. :-) - Marsh
