Cache Invalidation
After your data is cached, it usually remains in the cache until it expires. If the data changes at the source or shouldn't be cached anymore, you might want to clear the cache before its expiration time. You can do this by initiating a cache invalidation request through the Cache Invalidation Request form. For more information, see Cache Invalidation Request.
In some cases, an automatic cache invalidation is triggered, so you don't need to do anything manually. For more information, see Automatic Cache Invalidation.
You can view the status of all cache invalidation requests on the Cache Invalidation Status page. For more information, see Cache Invalidation Status.
Cache invalidation doesn't affect the browser cache. For example, when you invalidate cached content, new customers see the new content right away, but returning customers still see the old content until it expires in their browser cache.
