Refresh your cache 101

If you can’t immediately see any of the changes that we’ve made to your website, it might be a good idea to check that you’re viewing the latest site data.

On the internet, a hard refresh is required almost any time there are design or development changes made to your website, so for any website owner it’s important to understand what the cache is and how to refresh it.

If your site has undergone recent development, chances are that the browser has simply become confused about what’s new and what’s old. To fix it, you will need to “clear your cache”, use a “hard refresh” or ‘clear history from the beginning of time’!


What is the cache?

The cache is a file store designed to facilitate quicker access to files and data. Browser caching is the most common type of saving data that Internet users will encounter.

As browsers download webpages, they will check the expiry dates of the files it encounters (scripts, CSS stylesheets and images) to determine if an update is required. The browser will then replace old files with the latest to ensure recent changes are mirrored. It’s important to note that not all files expire, so while the browser’s default expiry conditions will apply, sometimes files are not refreshed even though they have actually been changed.

For most users, the caching process is brilliant as the websites they visit on a regular basis may not change very often so caching saves unnecessary page downloads. However, for website owners who view the website on a day-to-day basis, it’s likely that a change will be missed by the browser. This can make the browser look jumbled or not showing latest changes due to cross over between the cached files and the latest database data from the site.
