Sometimes a refresh during a cookie based managed session with breadcrumb trail doesn't alway grab the milk^Wimages.

During development of Blackboard courses (an online teaching aid/publishing/grading/lesson application) we would have to "clear the disk cache" and restart IE and Netscape 4.x to get the right images.

But if you weren't logged in to Blackboard... you would get the images proper everytime. Some were cgi/perl continuously updated/replaced on the server. With the login... flaky. No login not flaky. Both code bases were in the wrong at times during the session.
