About Browser History and Caching
A cache is a temporary storage area where frequently accessed data can be retained for rapid loading. A web browser cache holds copies of pages that pass through it - all items you have accessed or downloaded from the Internet, including images, sounds, Web pages, and cookies. These items are stored on your computer, usually in the Temporary Internet Files folder.
Why clear your cache?
You may occasionally encounter an error message, a "Page Not Found" display, a "Momentarily Unavailable Message" etc. This could be due to a problem with the system, maintenance, or a number of other reasons. If you decide to go back to this url later, you may see this same message even though the problem is corrected because your browser has pulled the page from your cache.
