I need a cookie which lets my site recognize a specific ANONYMOUS user has returned? Example: My site lets anyone post messages as ANONYMOUS. But ... I would like to recognize the difference between ANONYMOUS(user707) and ANONYMOUS(user881). And be able to recognize this difference "every-time" the ANONYMOUS user returns to my site.
YES, I know there are dozens of ways to defeat this identification, but for what I'm doing "close-enough" is "good-enough", I don't need "bullet-proof"
So, tell me about a cookie I can drop on a surfer's computer (the first time they visit) and re-query every time they return, to identify "them" as "them"?
