Whenever I have to do any troubleshooting with a website, the first step is always clearing the browser cache. In fact, if you’ve worked with Dahl House Designs for any length of time, chances are good I’ve said “have you tried clearing your cache?” when you’ve experienced a site issue! I have a love/hate relationship with the browser cache; when they work properly, they are incredibly helpful. But when they don’t? They can cause a lot of frustration.
In this post, I’m going to explain what a cache is, why you occasionally have to clear them, and how to clear your browser cache– trust me, it is easier than it sounds!
What is a Browser Cache?
Internet speeds improve year after year, but even with all the technological advancements, people still want things faster. A browser cache helps to accomplish that! It does this by storing some of the website files locally on your computer. By storing them, your computer doesn’t have to redownload them every time you visit the same site.
Here’s a scenario: imagine someone visits your website for the first time. When the user lands on the homepage, their computer connects to the hosting server and loads all of the page content. The amount of time this takes varies based on several factors, but generally, most sites will load in a couple of seconds. During this process, their browser will identify certain components of the website that it thinks are useful and download them to the cache.
Next, let’s say the person clicks on the “contact” link in your website’s navigation. When the user gets to the new page, their browser will recognize that some of the “contact” page components are identical to those on the homepage. So instead of having to download the same information a second time from the hosting server, the browser instead uses the file it has saved locally in the cache.
A good example of this is a website logo, like the DHD logo in the upper left screen of this page. Your computer may save this logo so that if you go to another page on the Dahl House Designs website, it will load much more quickly.
Why Might I Need to Clear My Cache?
So, what does it mean to clear your cache? Essentially, you are deleting those saved files off your local computer. There are a number of reasons you may want to clear your browser cache:
Website Error Troubleshooting
Browser caches are very helpful in terms of website performance, but they’re not perfect systems. Occasionally your browser cache can get confused, which may cause a web page to display incorrectly. In some cases, you may not see the most recent content on a site since the browser is continuing to use an old file that is being stored locally, or there may be other visual problems, like missing content.
An easy way to check if you have a caching issue is by opening the same website in an “incognito” window, which bypasses cached files. If what you see incognito isn’t the same as your regular browser screen, it’s time to clear your cache!
Security & Privacy
It is good practice to minimize the electronic trail you leave when public computers, such as those at a library. Clearing the browser’s cache when you are done is a practical action you can take to help minimize your risk of identity theft and hacking.
Computer Speed & Performance
Yes, your browser cache can help speed up a website significantly. But they can also get so bloated with saved data that they start to impact your computer’s overall performance. Clearing out your cache on a reasonably regular basis will help keep your machine running optimally.
