We are confident that at some point while troubleshooting website issues, particularly 304 errors, you have felt the need to ‘clear your browser cache.’ But do you truly understand the importance of a browser cache and why you must clear it?
If not, you are on the right piece. This article discusses what a cache is, how it works, and how to clear it on different browsers.
What is a Cache?
A cache is a small storage space that temporarily stores copies of frequently accessed data, so that it can be accessed faster instead of waiting for it to load again from the original server. It helps improve the speed and performance of websites and applications by reducing load times.
In simple terms, ‘cache’ is a dedicated space on your device where your browser stores files it might need again. If you visit a website, the cache stores its data, so when you visit it again, it loads faster than before. Without a cache, your browser would have to download several files from scratch every time, which can noticeably slow things down.
Here are the elements a cache stores:
- Background images
- Website logos
- Fonts
- CSS
- HTML, and
- JavaScript
These elements can accumulate into dozens, hundreds, or even thousands of files for a single website.
How Does a Browser Cache Work?
A browser cache works through the following steps:
- Starting a request: Let Firefox be our browser for this experiment. Suppose you visit a website, Firefox notifies the web server that it desires specific content from that website, a formal request.
- Cache consultation: Then, the browser consults its internal database, which is the browser cache in this case. It does this to see if any data from the requested website is already saved within this cache.
- Decision time: If the requested content is absent in the cache, Firefox will get it directly from the web server. This process is called a response.
- Cache triumph: If the requested content is present in the browser cache, Firefox will not engage the server. Instead, it retrieves the content locally from its cache.
You must make sure a browser cache holds accurate and current data for the desired webpage. If not, it becomes ‘stale,’ meaning it gets outdated. As many websites keep changing at times, old data can cause problems.
Your browser’s job is to clear and deliver content that currently shows the state of the website.
We already listed the crucial elements a cache stores, but it also uses more advanced storage systems behind the scenes. Along with basic resources like login credentials and site content, the cache relies on database structures like:
- Cookies
- IndexedDB APIs
- Cache APIs
- Web storage APIs and more
Why You Should Clear Your Cache?
Clearing the cache means deleting all of the stored data of a website. Here are several reasons why you may decide to do so:
1. System Efficiency
Depending on your settings, the cache can substantially occupy your disk space. As the cache expands, so does the drag on your computer’s speed when browsing.
By clearing your cache, you can easily free your disk space, making sure a faster website loading time and improved device performance.
2. Privacy and Security
Clearing your cache can help you protect your privacy when using a public or shared computer. If you don’t, malicious users could look into your browser history.
The cache stores private data from certain websites, so it could let someone else see your information if they access your device. posing a risk of the following user’s unauthorized access to sensitive information. Except just privacy concerns, these temporary files could become targets for adware, viruses, and malware.
3. Real-time Viewing
In theory, whenever you visit a website, your cache should check for updates, presenting you with the most recent pages. However, in reality, this process isn’t foolproof. There are instances when the cache loads older stored pages, leaving you with outdated content.
So, clearing your cache periodically helps your browser start afresh and makes sure you see updated pages and information.
4. Addressing Browser Problems
Your cache can also cause problems in your browser. For example, it can slow down the loading time of websites. You can resolve these errors and restore functionality to your browsing experience by clearing caches.
Optimising Cookie Management
Web cookies are small text files that websites secretly store in your browser. They are used to identify users, save site login credentials, or create personalized web pages according to your choice. It’s easy to check your cookie settings or even delete all your cookies when needed.
Here are a few reasons why you can consider clearing browser cookies:
- Enhanced security: Cookies could become a target of hackers. They can hijack cookies and access your browser extensions, so you should delete them every once and then.
- Privacy protection: Cookies collect personal information. Websites use this data to track your activities, and show you ads to target you specifically. Hence, clearing your cookies ensure you are in charge of your information.
- Protection on shared networks and computers: Failing to clear your cookies after each session when using public computers poses a risk. The next user may gain access to your browsing history. In extreme cases, not logging out of your online banking or shopping accounts could also expose sensitive information.
- Browsing speed: Your initial visit to a website results in pages being stored on your hard drive. This mechanism accelerates subsequent visits as the saved pages load without a full download. However, the accumulation of numerous cookies can affect your system’s speed.
Differences Between Cache and Cookies
Caches and cookies both work to enhance website performance. However, each serves a distinct purpose. Let’s discuss that below:
| Cache | Cookies |
|---|---|
| Cache helps to load websites faster by saving files like audio, video, and images on your device. | Cookies track various user-related characteristics to shape a personalized user experience. |
