--------------------------------------------

Interestingly addBufferedResponse() is not used anywhere. Do we still need it?

> The WebApplication uses the MostRecentlyUsedMap as a limited size cache. Elements of
> the cache are removed when a new entry is added based upon the age of the element's keys
> not on the age of the element's data.
> Naively, I would expect a high usage element (one's whose associated data keeps changing)
> should be kept in the cache rather than reaped - simply because it was enter earlier than some
> low activity but more recent entry.
> The MostRecentlyUsedMap is based upon the Java LinkedHashMap container. 
> As such, it is not a very good fit for data-based age cache.
> Of course I could be completely wrong in this case and it actually the age of the key that is
> important not how often the data associated with the key is changed.
