Clearing your browser's cache, cookies, and history

Each time you access a file through your web browser, the browser caches stores it. By doing this, the browser does not have to retrieve files (including any images) from the remote website each time you click Back or Forward. You should periodically clear the cache to allow your browser to function more efficiently.

A cookie is a file created by a web browser at the request of a website that is then stored on a computer. These files typically store user-specific information such as selections in a form, shopping cart contents, or authentication data. Browsers will normally clear cookies that reach a certain age, but clearing them manually may solve problems with websites or your browser.

A browser's history is a log of sites that you visit. When you press the back button in your browser, you are moving back one entry in the history log. Browsers will normally clear their history at regular intervals, but you may want to clear it manually for privacy reasons.
