What is a Cache? (Safari & Chrome)


A cache is the place where your browser stores images, code, and other files to avoid re-downloading them repeatedly. Your browser would run a lot slower without this feature, because every site you opened would require re-downloading tons of files. The cache stores all of these locally, to save bandwidth and speed up your browsing. Every once in a while, a site will stop working, and clearing the cache will fix it. Why does this help? Sometimes there’s a difference between the version of a website cached (stored) on your computer and the version that you’re loading from the web. This conflict can lead to weird glitches and clearing your cache can help when nothing else seems to.
