Why should we have to empty a cache at all, and what does that mean?
Because even after you edit and save a page, a browser might continue to hang on to (and display) an older versions of pages. It can be disconcerting to work on a page, click SAVE, and see... that your changes don't appear on the screen. The reason is that Internet browsers such as Internet Explorer, Firefox, Safari, Opera and others all share a common feature called 'cacheing'. This means that in order to help save time in loading pages, especially ones that have recently been viewed, the browser will save a copy of the page on your local computer. Then when the browser is asked to show that page again (if you push the 'back' button, for instance), it will show the stored copy rather than downloading the entire page again.
In theory, this is a good thing. It helps you to view webpages at a higher rate of speed. This can be especially convenient when viewing a really large (really) website like ours. When it's not convenient, just refresh the page.
