Use it for what? The computer uses it depending on the user's settings. For example, if I tell the browser to check / download a URL everytime I visit it, then it should download each image, CSS, JS etc. However, if the same image is used a few times on that page, it is downloaded once to help speed up the process.

Then it is ASP you are referring to (moved to the ASP zone). It sounds like you need to check the session / cookies to see if the user is logged out, not necessarily the HTML cache.
ASP 101 has some samples to take a look at on how to check cookies / sessions, depending on what you are using.
