the bug summary as written is invalid. see bug 162545 (which is a duplicate). see also: http://www.mozilla.org/projects/netlib/http/http-caching-faq.html Adam: to get the behavior you are expecting, the site must specify "cache-control: no-store" in its response. otherwise, Mozilla is allowed to cache the documents for the purposes of back/forward navigation. *** This bug has been marked as a duplicate of 162545 ***
