Caching – what is it?

I came across an article over at today which I thought would make a good blog post.

The article was about caching, which is quite a common issue that crops up in web design.

To put it very simply, caching is when your internet browser remembers parts of the web page you visited and stores a copy of them on your computer. Next time you view the web page your browser will load parts of the page from your cache, to speed up loading times.

Sometimes we will make a change to a website, but the website will still look the same as before. 99 percent of the time you can solve this by holding down CTRL and F5 at the same time. This tells most browsers to reload the page in it’s entirety, so you should now see the changes.
