 Invalidating by `key` won't work if you're using tags. In that case, you should invalidate by flushing the tag.

-### Tag
-
-By specifying `tags`, you can invalidate it programmatically. You must be using a cache driver that supports [tags](https://laravel.com/docs/8.x/cache#cache-tags), like Redis or Memcached.

-Similar to invalidating by a key as explained above, you can flush all keys that use the tags.
-
-```php
-Cache::tags('home')->flush(); // invalidates first and second pair
-Cache::tags('stocks')->flush(); // invalidates first and third pair
-```

-:::warning
-Don't use the `key` and `tags` parameters together.

 ### Cache clear
 
 The contents of your cache tags are stored in the application cache. Clear that, and you'll see fresh content next visit.
