One disadvantage of browser caches is that they may not be up-to-date. As a user, you cannot know when webmasters will update individual subpages or even entire websites. The resources stored in the cache may be out of date after updates.
To avoid the problem of lack of timeliness, both webmasters and users are responsible. Webmasters decide whether they want to use caching and which cv data resources should be cached for what period of time - we will discuss how webmasters correctly define the rules for caching in the next section.
While webmasters are encouraged to select only static resources for caching to ensure data freshness, users have the responsibility to clear their cache regularly . Clearing the cache will delete all stored content in the cache.
If a page is reloaded after the cache has been cleared, all updates to this page will be displayed. The updated and therefore new static resources are also stored in the cache so that new content is loaded from the cache the next time. Regularly clearing the cache also has the advantage of reducing the load on the end device's hard drive and, as a result, improving the end device's performance.
