When visitors first find a website, all of the site’s digital assets load up at a certain speed. Sometimes, these speeds can be slower than average. However, when the user comes back, they will likely experience faster loading speeds. This is due to data and browser caching (cache is pronounced “cash”). This example may seem a bit vague, though. So, if you’re wondering what it means when something is cached, you’ve come to the right place! In the section below, we’ll answer some of the most common questions about cached data. 

Cache Data Explained

When you visit a website, all of the data is placed into a storage container in your web browser on whatever device you’re using. These data are temporary files and provide a sort of snapshot of the site you’ve visited. By caching a website’s information, websites load faster upon subsequent visits. This is because you aren’t loading and reloading every single file whenever you visit a site. Rather than loading these files individually, cached data reloads the entire page as a single unit in a single go. 

What Can Be Cached?

The short answer to this question is “a lot of things.” Individual sets of data can be cached. Entire web pages can be cached. Browsers and servers host cached materials and in a sense can be classified as cached themselves. Each of these elements are cached differently and for different reasons. However, the end goal is usually the same: to improve the user experience and to improve loading speeds. 

What Is Cached Data?

Cached data is any data from a website that is temporarily stored onto your device. Image files, graphics, script, and gifs are all examples of cached data. When you first visit a website, your browser will load and then catalog every piece of data. If there are large assets on the page, the load time might be longer than average. Fortunately, when you return to a website, the cache retrieves the data at a faster speed because it has already rendered it. 

What Is a Browser Cache? 

A browser cache is what enables cached data to be stored properly during a website visit. Again, this makes the loading times for subsequent visits faster because the browser retrieves data that has already been rendered. Whenever you visit a website, the browser you use rips the following assets from a given webpage:

  • Image Files
  • Metadata
  • HTML Files
  • CSS Style Sheets
  • JavaScript 
  • Mixed Media/Multimedia

Browsers store these data locally on your device. Whether you are using a desktop or smartphone, browsers cache data onto the hard drive for later retrieval. 

What Is a Server Cache?

Much like browser caching, servers cache content as well. However, unlike a browser that saves data on the user-side, server caches store data on a website’s server. These caches do not require involvement from a specific user or their browser in any way. Some items that servers cache involve the following elements:

  • Objects
  • Content Delivery Networks 
  • Networks of Code
  • Data Sets & Datasheets

Server caches are unique in that they document and register changes made on the developer’s end. Often, when a company asks a web hosting company to update their website, the changes will take some time to register on a live page. This is due to the old information still remaining active on the server’s cache. Once the cache clears, the new information will register. 

Why Do I Need to Clear My Browser’s Cache?

As stated above, when you access a website you’ve visited in the past, cached information will usually appear on your browsing device. If you’re looking for changes made to a page, but they aren’t showing up, there’s a pretty good chance that you haven’t cleared your browser’s cache. If you haven’t cleared it, your browser will continue to retrieve old and outdated information. Remember: your browser wants to help cut down on load speeds by retrieving data. If you’re looking to view new changes on a website, you’ll have to clear out your browser’s cache. This process is different across browsers and devices (e.g. iPhone vs. desktop computer). 

How to Clear Your Desktop Browser’s Cache

When it comes to desktop browsers, two main browsers control a majority of the market share. These browsers are Google Chrome and Apple Safari (these two constitute around 85% of the total market share).

If you are using another browser and don’t know how to clear your cache, be sure to reach out to our support team
