Why clear or refresh your cache?
Your browser has a folder in which certain items that have been downloaded are stored for future use. Graphic images (such as buttons and icons), photos and even entire web pages are examples of items which are saved or cached. Even websites which are highly optimized for speed are likely to load a lot of files at any point to display the content in your browser. When visiting a webpage your browser checks if a copy of the files on the page is in its cache already. If so, it will save the visitor some downloading time and make webpages load faster. Some browsers refer to it’s cache as Temporary Internet Files.
Browsers try to do their part to speed up the loading process. The first time you visit a site, the browser will save pieces of the site, because the browser can display the files stored in its cache much faster than it can pull fresh files from a server. The next time you visit that site, the cached files will help cut down the page load time.
Refreshing your cache
There are some situations when bypassing your browser’s cache is preferred. Just clicking the refresh button (or hitting F5) won’t be sufficient in this case, because this reloads the webpage while still using the old files from the cache. You need to refresh your cache first! Many times web developers have to make updates to the files that comprise your site in order to push a change or new feature live. If we change a file that your browser has cached, it’s going to keep serving the old, cached version of the file and you won’t see our most recent changes.
Below are links to pages that explain how to clear the cache for the most popular internet browsers.
Be sure to check the box for Cache only so you don’t delete other data you may want to keep!
