Clearing Cache

Before you start using a Webstudies (WebCT) module, you should make sure that the settings on your personal computer are correct in order for Webstudies to run smoothly without problems.

You must do the following: Enable JavaScript - make sure you have the correct version of Java (more information), disable all pop-up blockers and it is very important to reset the cache of your browser.

What is the cache

The Temporary Internet Files (or cache) folder contains web page content that is stored on your hard disk for quick viewing. This cache permits Internet Explorer or any other browser to download only the content that has changed since you last viewed a Web page, instead of downloading all the content for a page every time it is displayed.

Sometimes however the files stored in your Temporary Internet Files folder can include small malicious applications and viruses that cause problems with your browsers. These files also affect the storage on your computer itself and can lead to low disk space.

It is therefore very important to clear the cache as often as you can.

Please scroll down to see the steps on how to clean the cache.
