Web browsers often store some piece of web data temporarily to help improve users’ browsing experiences.
Browsers typically store static web content—website data that doesn’t change from visit to visit—in the computer’s hard drive and serve it to visitors when they revisit instead of loading it from the server.
Cached web data helps speed up the website, making browsing more seamless.
However, some cached data could get outdated with time and require clearing the cache to make the browser store the updated data. This article guides you on clearing the cache in different browsers.
So, let’s get to it.
Importance and Pitfalls of Clearing Browser Cache
Clearing your browser’s cache comes with some huge benefits and some pitfalls.
Let’s quickly examine them, starting with the former :
- Browser caching saves web data on your local hard drive, making browsing faster than retrieving them from the remote server.
- It reduces bandwidth consumption which helps decrease network congestion.
- Caching helps reduce remote server workload.
- Caching web content lets users obtain the cached copy when the server breaks down.
Now, here are some of the things we don’t like about browser caching :
- It only serves visitors the saved version in the cache, making visitors see the outdated version when the cached data fails to update correctly.
- The outdated scripts, styles, or files could lead to bugs, page display issues, or incorrect page loading.
- Browser caching could store sensitive data and private images in the local hard drive exposing them to criminals that can read cached files.
- Caching saves data on your hard drive, eating up your storage space.
