Hi,

The following should do:

CacheManager.Insert(cacheKey,
                    objectToCache,
                    new CacheEvictionPolicy(
                        new string[1] {DataFactoryCache.ChildrenCacheKey(parentPage.ContentLink)},
                        TimeSpan.FromMinutes(5),
                        CacheTimeoutType.Sliding));

Thanks, M

Hi,

DataFactoryCache.ChildrenCacheKey is deprecated, so I used IContentCacheKeyCreator.CreateChildrenCacheKey instead. Like this;

var expiration = TimeSpan.FromSeconds(timeoutInSeconds);
var cacheKeys = new List<string>() { _contentCacheKeyCreator.CreateChildrenCacheKey(contentReference, null) };
var evictionPolicy = new CacheEvictionPolicy(expiration, CacheTimeoutType.Absolute, cacheKeys);

The problem is that the cachekey generated from CreateChildrenCacheKey only covers the child pages. I want my cache to be refreshed when ANY descendant page is updated.

I created my own caching invalidation for this reason (you can have descendants and also contenttype as dependency). Then in content events I check updated/created/deleted/moved pages and invalidate cache. It was for an older version though. I'll try to blog about it in a few days and port it to the latest version :)

Thanks Daniel! Using contenttype as dependency might work for me.

Something like this using master keys and content events...
