It is important to remember that the Cake will clear a cached view if a model used in the cached view is modified. For example, if a cached view uses data from the Post model, and there has been an INSERT, UPDATE, or DELETE query made to a Post, the cache for that view is cleared, and new content is generated on the next request.

If you need to manually clear the cache, you can do so by calling Cache::clear(). This will clear all cached data, including non-view data.
