The above security message is no longer useful, and gives users a false sense of security. Closing your browser will no longer remove the cookie. Unfortunately, browser developers thought it useful to make closing of the browser not constitute "end of session" anymore. I do not know why they did this. I thought the cookie spec was very specific about that, but it's been so long since I looked at it.

Does anyone know of a way of making browsers honour what we all once held dear?

It was suggested on the shib-users mailing list that we should change cookie expiration policies from "expires at end of session" to "expires at time XYZ". At least browsers will honor a time-based expiration, for now!

The only obvious problem is time being out of sync on client computers.
