Unfortunately if you were to turn cookies off you would be unable to login, stay logged in, or do pretty much anything...
A JavaScript "approve cookie use" code from freely online would be the perfect scenario, as the site just won't work if they don't allow cookies to be set. I myself have used the one at shareaholic before but it works the same as Isaac's suggestion.
The usable internet requires cookies, just disable them in your browser and let me know how fast you re-enable them while you're trying to use the internet as you would normally.
