When using the internet, pages you have visited are
stored in your computer's "short-term memory" cache. If you return to a page,
your computer may pull your view of that page from cache memory, rather than
load a fresh view of the page from the site. This can be a concern when using a
secure site, since confidential information may be stored on your computer in a
non-secure format. We recommend that you clear your browser's history folder,
any Temporary Internet Files, and your computer's disk cache each time you exit
this secure site.
