What is Cache?
The word 'Cache' refers
to the temporary storage area in memory or
on disk that computer components and various
programs use to quickly access data.
Browser Cache
A web browser saves the
pages you view on the internet to your pc's
hard disk. When a browser is installed a
subdirectory is created under the main
program directory to cache visited pages.
Caching is a quick way to speed up your Web
surfing by storing the pages on your hard
disk. By having the page data stored
locally, your browser can access the page
right from your PC rather than waiting for
it to download from the web. This means the
next time you access the same page on the
internet, it loads quickly from your hard
disk. This makes information appear much
quicker.
There are several problems associated with
cached pages.
1. After a lot of browsing, your hard disk
can become loaded with thousands of files.
Caching makes for faster browsing but
depending on your computer it can slow down
your hard drive.
2. One of the most common problems reported
to us by site visitors is that they are not
looking at information that is up to date.
This is normally due to users looking at old
'cached pages' or 'temporary internet files'
stored on their own computer—therefore the
user may not be seeing the latest published
information from our web server. Ensure your
browser settings are showing you the latest
information by following the Recommend
Browser Settings below.

Settings
MICROSOFT INTERNET EXPLORER
Look for 'Internet Options' under 'Edit' or
'Tools'
Under the General Tab, you will see a
'Temporary Internet Files' section.
Select 'Settings'.
Look underneath 'Check for newer versions of
stored pages'

Under the same section (General Tab) select
'Delete Files'. This will remove any
currently stored pages from your computer.
Click 'OK'.
To make these changes take effect you will
need to close and then restart your browser.
Tips
Try these steps to clear
'cached pages' or 'temporary internet files'
that may be stored on your computer. 'Right
click' over the offending page and select
'refresh' (Microsoft Internet Explorer) or
'reload' (Netscape) in case your browser is
giving you a previously cached copy of our
page.
You can reduce percentage of disk space used
by Internet Explorer for its cache by
sliding the "Amount of disk space to use"
gauge.
Although it's not required by all browsers,
restarting your browser after clearing the
cache is a good idea.
Clearing the browser's cache will slow down
the time it takes to load sites you've been
to before, but it will speed up the time it
takes for your browser to load when you
launch it.
Navigator 3.x and Communicator 4.x users -
If you're often having to reload frequently
updated pages, try setting 'Verify
Documents' option to 'Every Time'. This will
make the browser retrieve the latest copy of
a web page even if it is in your pc's cache.
Proxy Servers at
Internet Service Providers
Please be aware Internet
Service Providers may use proxy caches to
reduce their latency and traffic. This is
beyond our control and may also be the cause
of your browser showing older versions of
pages.
