You may have to manually login as a security measure for the first time after clearing your cache.

What is Cache?

Cache is place on your computer where active data is temporarily stored to shorten access times. In other words, cache keeps data that is frequently requested and accessed by the system. It is, therefore, saved in dedicated quick-to-access storage to reduce the time taken to retrieve the data. Results? Better latency and improved I/O (input/output). This has a direct impact on app performance as most applications are dependent upon input and output operations.

Web Browser Cache

In web browsers, for example, frequently visited webpages are cached to improve performance. To load a webpage, your browser will then be able to access locally stored data, instead of having to request it be sent again. To see cached data at work, try clicking “return” to go back to the previous page. Your browser will be able to recover most of the files it requires from cache. It will also read cache at a far quicker rate than reading the files from the webpage again.

Why Do You Need to Clear Cache?

While cache is beneficial by design, it isn’t perfect. Its imperfections can lead to an opposite effect and cause issues with forms, logins or even entire webpage data. This happens when cached data gets outdated or altogether corrupted. The browser then wastes time trying to fetch corrupted data or reading an old item from the cache. An immediate solution to the issue is to clear out cache and let your browser rebuild a new one.  

What Time Range Should I Select When Clearing Cache?

This will depend on how long ago the site was last accessed and when it changed. We recommend going as far back as possible to clear everything to ensure a fresh start.
