---------------------------------
Jon, could you please elaborate? Are you suggesting changes to CachingHttpClient or extending from it to do this?

> When creating a ResponseHandler to parse the response value into a usable java object, I notice that the code is executed every time, even if the response object is served from cache. It would be nice to have a system where a ResponseHandler can be written such that its value is also served from cache. This may require a different interface which:
> - Exposes just the values which are not altered when served from a cache
> - Returns objects which can be cached out of process ( through documentation, and having the return type extend Serializable)
> Alternatively, if there is a header uniquely identifying a response, a WeakHashMap could be used to provide a cache associating a response with a created object (although such a cache would not correlate to the HTTP cache in terms of retention)
