Website Caching: What You Need To Know

Do you use a web page and wonder why all of a sudden it doesn't work properly? Maybe updates were made to the website but you’re still seeing the older version? This may be a signal that you need to clear your cache.

What is caching?

Caching is the process of storing copies [of files, data, etc.] in a temporary storage location to be quickly accessed by your web browser. Each time a user loads a webpage, the browser downloads a large amount of data to show the information and content on that page. To speed up the page loading time, web browsers will save or cache a copy of the content on your device’s hard drive. Caching allows you to efficiently reuse previously retrieved data.

What does caching do, and what does clearing the cache accomplish?

Web browsers cache HTML files, JavaScript, images, and more to help websites operate faster and more efficiently. “Clearing the cache” means that the memory of the page is deleted from your device’s hard drive. The next time you visit that webpage, it will load as if it’s the first time you have visited that page.

How to clear the cache

Clearing the cache will look different depending on your device, but you will need to visit your device’s browser settings. See below for step-by-step instructions to learn how to clear your cache.
