Hi, I am interested if it is possible to invalidate whole cache zone. Now it is possible to invalidate single cache item using cache key and third party module Cache Purge. What I need is to remove all cache items when hitting some location. So far the ideas are next:
1. remove cache folder, but then you need to restart nginx.
2. create several cache_zones and use the one stored with the name stored in memcache. So when cache needs to be invalidated the backend will update cache_zone name record stored in memcache. It seems to be like a possible way, but have no idea how to implement it.
