What is a browser cache anyway? It’s a place on your computer hard drive where your browser keeps things it downloaded once in case they’re needed again. What this means is that if there is a change to a website, and your hard drive does not have the latest version of the change, you will not see the change until you CLEAR YOUR BROWSER CACHE.
Clearing your browser cache with wipe your hard drive of the old website elements and add the new ones in its place.
An empty cache means there’s no confusion. As you visit websites moving forward, the browser will download fresh copies of everything you see on each webpage.
Generally speaking, this is not something you need to worry about. Unless you know there has been a change to a website and you need to see the change right away.
This happens when we are designing and building a new website OR making updates to a website for a client. The client wants to see the changes right away, not wanting to wait until the hard drive downloads the latest version. This is where clearing the browser cache comes in handy.
Here is a link that gives you step by step instructions on how to clear your browser cache.
