/** Encapsulate a response. Instead of directly returning the FILE pointer
from which a response is read, return an instance of this object. For a
simple system where all that needs to be done to free the stream and its
associated resources, this is overkill. However, some streams may require
complex operations to free their resources once the client is done with
the stream. Those classes should return a subclass of Response
which has those operations built into the destructor.
@todo If the code that parses the MIME headers was moved from Connect and
HTTPConnect to this class and its children, it would be easier to build
a FileConnect class (or maybe the specifics of the connection type could
be held in the Response object and HTTPConnect and the to be written
FileConnect would not be needed). */
