What is Browser Cache?

The browser cache is a temporary storage location on your computer or device where a web browser saves copies of web pages, images, stylesheets, scripts, and other elements of websites you visit. This is done to improve your browsing experience by speeding up the loading time of frequently visited websites.

When you visit a website for the first time, the browser downloads all necessary elements like images, text, and JavaScript files from the server. On subsequent visits, the browser retrieves these elements from the local cache rather than re-downloading them from the web server. This reduces load times and minimizes data usage.

When Should You Clear Browser Cache?

You don’t need to clear your cache every time you browse the internet, but there are specific scenarios where it can be useful:

• When websites aren’t loading correctly or are displaying outdated content.
• After updates or changes to a website you frequently visit.
• When your browser is slow or experiencing performance issues.
• If you're troubleshooting login or session issues.
• When you're clearing space on your device.

Why Clearing Your Browser Cache Helps Common Issues

Despite its benefits, there are situations where the browser cache can cause problems. Including:

• Outdated or Corrupted Files - Over time, the cache can store outdated or corrupted files. If the website you're visiting has been updated with new content or design, but your browser is still using old cached files, the page may not display correctly. You might see broken images, outdated information, or even experience errors on a site that is functioning perfectly for others.
• Page Not Updating - If a website has undergone design changes, bug fixes, or updates, your browser may continue to show an old version of the page due to cached files. By clearing the cache, you force the browser to fetch the latest version of the site, ensuring you see the most up-to-date content.
• Slow Performance - If the cache becomes too large or filled with unused files, it can slow down your browser. This may result in longer load times or even sluggish performance when navigating between pages. Clearing the cache can help restore your browser’s speed and efficiency.
• Login Issues or Errors - Sometimes, cached files related to login credentials or session data can cause issues. You might find yourself logged out unexpectedly, unable to log in, or stuck on a particular screen. Clearing the cache can resolve session conflicts and ensure that your login credentials are refreshed.
• Fixing Broken Site Features - Some interactive features or dynamic content on websites (like videos, animations, or pop-ups) might not function properly due to conflicts between cached files and newer updates to the site. Clearing the cache can fix issues such as broken JavaScript, missing elements, or malfunctioning features.

If you continue to experience issues even after clearing your cache, you might want to check for browser updates, disable extensions, or contact IT Help Desk (865-594-1830 or an IIQ Support Ticket).
