I know that Session id and cookie are used to track user behavior and are used by most websites as a marketing strategy. However search engines spiders don't accept them.
This however sounds like a kind of cloaking. For instance, if I have a couple of links on a page and don't want spiders to crawl them, I may make the process of enabling session id and cookie mandatory and not let spiders crawl it. Isn't that possible?
