Hi Scott,

Because of the way that the cache works, sending the authoritative  
request after deleting the handle would not have any effect.  Setting  
the authoritative flag means that the resolver (in this case in the  
server) bypasses the cache when resolving the handle but it does put  
the result of that resolution back into the cache.  Because the handle  
had been deleted, there was nothing to put back into the cache.  The  
resolver didn't delete the old cached value, but it would have if the  
handle hadn't been deleted.

Thanks,
Sean
