Priorities are hints that can optimize cache scavenging. Essentially,
if the ASP.NET engine decides to remove cache items because memory is
scarce, it will remove items with a lower priority cost first. The
CacheItemPriority enumeration also includes a
NotRemovable member that you can use to prevent
ASP.NET from removing an object from the cache automatically when
memory is low.

public enum 
CacheItemPriority  {
Low = 1 ,
BelowNormal = 2 ,
Normal = 3 ,
Default = 3 ,
AboveNormal = 4 ,
High = 5 ,
NotRemovable = 6 
}
