# Troubleshooting Cache ## What is caching? Each web page is read thousands of times more often that it is changed. Caching or using caches helps your site perform run much faster. A cache is a version of a webpage from some time in the past which assumes that the page has not been changed - and as a result does not go all the way back to our servers to check. Most caches update automatically over time - but sometimes you want to make changes get pushed out faster. The instructions above show you how to clear each kind of cache manually to help in testing and diagnosing problems. ## How to Clear your Browser's Cache Some browsers will hold copies of pages that have been visited before to improve performance. Select your browser for detailed instructions on how to clear cache: * [Google Chrome](https://support.google.com/accounts/answer/32050) * [Mozilla Firefox](https://support.mozilla.org/en-US/kb/how-clear-firefox-cache) * [Microsoft Edge](https://support.microsoft.com/en-us/help/10607/microsoft-edge-view-delete-browser-history) * [Safari](https://support.apple.com/guide/safari/manage-cookies-and-website-data-sfri11471/mac) (macOS) / [Safari](https://support.apple.com/en-us/HT201265) (iOS) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
