Determine when application cache item will timeout?

In ASP.NET, when storing a value in the application cache with absolute expiry is there a method to retrieve the date/time when the item will expire? The application cache item will be refreshed if expired based on user requests.

use the CacheItemRemovedCallback; your object may get kicked from the cache earlier than you expect anyway

There is a method signature on the HttContext.Cache object which allows you to specify a method to be called in the event that a Cached item is removed when you set a new Cache item.

Define yourself a method that'll allow you to process that information, whether you want it to re-submit the item to the Applcation Cache, email you about it, log it in the Event Log, whatever suits your needs.

Hope that helps, Pascal

Not sure if I've understood your question right, but I'll give it a try: I believe there is no way to actually figure out, when a certain cache-item is going to expire. In most scenarios, I use a delegate passed in as a parameter (CacheItemRemovedCallback) when adding objects to the cache, so I get notified when the item gets kicked out.

Hope this helps a bit.
