Caching is the process of storing data in a temporary location to improve access speed. This can be useful for frequently accessed data, such as website content or database queries. However, caching can also cause problems if the data changes frequently, as the cached data may become outdated. To avoid caching, you can use a number of techniques, such as setting headers to prevent caching or using a cache-busting mechanism.
Avoiding caching can be important for a number of reasons. First, it can help to ensure that users are always seeing the most up-to-date information. Second, it can help to improve performance by reducing the amount of time spent loading cached data. Finally, it can help to improve security by preventing attackers from accessing cached data.
