Re: Good
Unless the site has a login you are using there is NO good reason for a cookie.
You need to distinguish between persistent and temporary cookies. One of the most common uses of cookies is to preserve state between requests. Even without any login, any site that isn't just brochureware probably needs session state. It's possible to preserve state without cookies using request and response data, but this is really just a diy cookie.
When properly implemented, session cookies are harmless. Their lifetime and accessibility should both be limited to the current session.
