True, but it's not obvious to non-techies (hence the article). I was curious how FB did logins when we were creating our API and site since I couldn't fathom them sending l/p's without https. A long look at their source on the homepage is really all it took to guess what they did (a guess, I could still be wrong). After a good deal of painful eyestrain I noticed they seemed to be using their internal APIs via JS over https for authentication. I wonder how many "non-https" sites also do this. I'd still wager a good deal of sites still send authentication over plain ol' http though. Is the lag for authentication purposes really that bad? Anyone have any hard metrics?
