Gateway Policy: Remove from Cache?

[Anon Anon]

Hi,

 

I have a simple and straightforward question that I can't seem to find an answer for elsewhere.

 

In our policies we use caching assertions (Store to Cache/Look Up in Cache) for reading and storing data in the gateway cache.

Sometimes we need to invalidate items in the cache.

 

How can I remove an item from the cache based on a cache key?

 

BR,

Tony

If the TTL does not deal with your removal, to "remove" you just do another "put" into the cache with a STATIC value like "INVALID". You can then check that value if you get another cache hit.

Nice Idea!, never thought of this....

 

i do agree that this feature should be added, feel free to create an Idea for it and don't forget to vote on it yourself. Andy's suggestion is a nice workaround.

 

There is a way to invalidate All cache, if this is helpful. Just increment the number in the messageCache.resetGeneration cluster wide property. This will invalidate all local cache on the gateway.

Updating the cache entry and setting the Maximum Entry Age to "0" should remove it.  I think this is what Andy was suggesting with the TTL.
