Nardo brings up a good point about the domain portion of the cookie...one I haven't run into because I redirect .domain.com to www.domain.com on all my servers.

As far as I can determine you cannot access the path or domain portion of the browsers cookie, to set yes, to read no.

Assuming it is the domain portion that might be a problem, you could force everyone into either www.domain.com or domain.com - that should *eventually* solve the problem.

But even if you go through and expire all the cookies of folks who log on, and rewrite them in a very exact way, it still might take a year to eliminate them all.

You might want to add a path and domain to where you are setting the cookies as a start (will not solve the problem of people with duplicates...), that way the browser cannot make it's own determination of those items.

But as far as solving it completely I cannot be of assistance.
