Lesson 17. Using Internet Explorer 5 > Understanding Caching

Understanding Caching

A cache is a storage area for often used information. The idea of a cache is that, by storing the data you use often in a convenient place, it takes less time for your computer to retrieve that information when you need it.

It works like this: When you use IE5, pages that you visit are cached and stored in the C:\Documents and Settings\your name\local settings\Temporary Internet Files folder. Then, when you use the back and forward buttons on the toolbar, the pages you previously visited load more quickly. This is especially noticeable with a page that contains a lot of graphics. When you re-visit a Web page with lots of graphics, you won't have to wait for all of the graphics to load again. Instead, IE5 finds the graphics files stored in your Internet Temporary Files folder and simply loads them from there, without attempting to download the graphics from the Internet.
