Every website is composed of hundreds or thousands of files. Therefore, a website will load a lot of files to display in a web browser the content of each individual page belonging to that website. This is even true for websites that are optimized for speed.
Browsers also try to speed up the loading process. Each browser saves pieces of the site in its cache. This allows the browser to display the files much faster than if it has to pull fresh files from the server each time you look at the same page. Every time you visit a webpage your browser checks to see if a copy of the files for the webpage is already in its cache.
Website managers or developers often make updates to websites to add new features, to make changes to web pages, to update the programs (applications) that make up the website, or for security purposes. If you don’t regularly clear out the cache for your browser, it will display the outdated version of the files rather than the latest version of the files for a website. Often this causes you to encounter browser errors such as run time errors, buttons missing on a page, the inability to enter data or save information, actions that don’t perform or respond appropriately, etc.
Please understand that just refreshing a page is often not sufficient to get the latest version of the website because it typically just loads the outdated files while reloading the webpage. Therefore, you need to actually clear the web browser’s cache.
Clearing out the cache and cookies on your browser(s) will help:
- prevent or resolve the issues caused by files in the cache not matching the update files of a website. This helps resolve issues because if forces your browser to download all the latest data from a website.
- prevent or resolve many performance issues by allowing your browser to function more efficiently.
- recover disk space on your device. This is especially helpful on mobile devices as they don’t have as much storage as laptop or desktop computers.
In summary, it’s important to clear your web browser’s cache and cookies, and to do so frequently. But REMEMBER, it is very important to remember to pay close attention to the options you choose when clearing caches and cookies, which is often based upon both the web browser and the device you are using to browse websites. If you save passwords, make sure you choose the correct option or your saved passwords may also be deleted.
