I seem to have found another "bug" with the Bigfoot/Bellsouth Webmail.
Users can log back into the service from cached pages.  This is a huge
security hole, especially for users access these services from public
terminals.  Subsequent users can just use the back button to go back in the
previous session history and log in as the previous user.


This is not uncommon in web based email & conferencing packages, however,
most are authored to only allow this for a certain amount of time and to
disregard the attempt if the user logged out properly.  Out of curiosity,
did you test this with the two variables of time and a logout?
