To speed up web browsing, your browser will download and keep copies of your webpage locally on your device. This is known as “caching”, and the saved files are referred to as the “cache” in an area called “cache”.
When you visit a page for a second time in a short period, you will see a saved copy stored in the cache rather than a fresh copy from the website.
This means you might not always be seeing the latest version of a webpage.
