About cache, cookies, and history

Each time you access a file through your web browser, the browser caches (i.e., stores) it. By doing this, the browser doesn't have to retrieve files and images from the web site each time you click Back or Forward.

A cookie is a file created by a web browser, at the request of a web site, that is then stored on your computer. These files typically store user-specific information such as selections in a form, shopping cart contents, or authentication data.

A browser's history is a log of sites that you visit. When you press a browser's Back button, you are moving back one entry in the history log.
