Cached web pages
If you can only view an old (outdated) copy of a web page which you believe has
been updated, you should take note of the following:
Your web browser has a page caching mechanism which stores previously viewed web
pages for faster viewing when re-visiting that page. Your PC may have the old
version of the page cached. Depending on your web browser's option settings this
old version may be presented to you when you view the page again. In order to
bypass the cached page in your PC's cache and see the updated page directly from
the web site, you can "refresh" your web page - F5 will do it.
If this fails to present the updated page that you know has been changed, you
can contact your Internet Service Provider (ISP). Most of them use a PROXY
SERVER to cache web pages viewed by their customers. It achieves the same thing
as your web browser’s caching mechanism but works for everyone who visits that
page, not just you. Their settings for retention of their cached pages may not
be appropriate (i.e. too long).
