HTTP Response Error: 404, Unexpected System.NullReferenceException: Object reference not set to an instance of an object


After restoring content database, we were getting 404 error into one of the web front server. We all were surprised to see this error because we followed same exact steps for restoring content database.  We have found issue is related to web front end server caching.
