The "PHPSESSID" thing is why many message boards couldn't be archived in wayback machine.

RFC 2109 predates anything that vaguely resembles PHP, and Netscape (thus, defacto, basically everyone using the internet), had cookies 3 years before the RFC. PHPSESSID wasn't added until PHP 4 in 2000.

If you're going to be a bitchy pedant, you'd damn well better be CORRECT.
