Clear your Cache (sounds like cash)

What is Cache?

No...don't clear your cash...then you'll be broke! Instead, there are times that you need to clear (another kind of) cache on your computer.

Cache is actually stored copy of a web page that remains in your computer so that your browser can load it whenever needed. And it is well known that browser cache plays an important role in browsing the web.

It stores the text, pictures, sounds and objects on the Internet and helps the browser to get them back from its cache whenever you need to go back to the same pages in the net. Browser designers noticed that most web sites had many of the same elements on multiple pages. So the thinking was, why download the same things...such as logos for every page? Why not just download it once and then keep it so we can use it again?

That’s what the browser cache is for. The cache is nothing more than a place on your hard disk where the browser keeps things that it downloaded once in case they’re needed again.

The cache has a size limit, which can be configured. When the cache gets full, the items in it that haven’t been used in a while are discarded to make more space.

Clearing the cache just means emptying it, so that the next time you display a web page everything must be downloaded anew. For reasons that we can't explain – other than by saying “stuff happens” – the cache sometimes get confused. This seems to happen to most browsers and at random times. What you’ll see are partially loaded or badly formatted web pages, incomplete pictures, or, in some cases, the wrong picture in the wrong place.

It’s not always a caching problem, but because it happens often enough, “clear your browser cache” is often one of the first diagnostic steps you’ll hear from people like our Service Desk team.
