Setting auto expiring cache from app_code folder   

I would like to store an object in cache for precisely one hour and then it 
expires. I have tried the following code but it seems to disappear after 
20mins...

HttpContext.Current.Cache.Add("bloggedAPI_Blocked_" + strEmail, myobject, 
null, DateTime.Now.AddHours(1), System.Web.Caching.Cache.NoSlidingExpiration,
System.Web.Caching.CacheItemPriority.NotRemovable, null); 

I need to set this from a method in my app_code folder and am wondering if 
its something to do with HttpContext.Current erasing the cache when the 
session times out?

Anybody know where I am going wrong?
Paul.

RE: Setting auto expiring cache from app_code folder   

Further testing and it seems that this does work intermittently. I’m guessing 
that maybe the asp.net application is restarting periodically which is 
causing the cached items to get lost. 

Is there a way I can tell when a specific application has restarted without 
having to put code in global.asx? event viewer perhaps?
