Ban Cache Invalidation
A URL pattern or header is an example of specific criteria that the ban method uses to invalidate cached content. Any cached content that meets the requirements of a ban request is immediately removed, and any ensuing requests for the content will be fulfilled directly by the origin server.
Benefits of Ban Cache Invalidation
- Allows you to selectively invalidate cached data without removing all cached data.
Challenges of Ban Cache Invalidation

Cache Invalidation and the Methods to Invalidate Cache
Cache invalidation is a state where we push away the data from the cache memory when the data present is outdated so do we perform this operation of pushing back/flushing the cache otherwise this still data will result in inconsistency of data.
When cached data gets stale or inaccurate, cache invalidation is the process of removing or updating it.. When the original data changes, the process of invalidating a cache involves deleting or updating cached data. It’s crucial because programs that rely on cached data may experience issues if it becomes outdated or erroneous over time.
