What is cache issue in web testing

Web browsers have caches, in which they keep pages after loading them, so that if a page is revisited, it can be loaded from the local server rather than from the remote server. This is a perfect system if pages never change. If pages do change, there is a problem: the page might change after a copy has been cached somewhere, so the user is presented with an old version. We can have a fresh version by pressing ctrl + f5 key or by deleting cookies/history of from the browser settings.
