    1.67 -/**
    1.68 -An abstract protocol handler.  Protocol handlers are required to
    1.69 -act as the bridge between abstract representations of sessions, transactions and
    1.70 -headers (the client side of the HTTP architecture) and specific comms transports
    1.71 -(the network side of the architecture).
    1.72 -
    1.73 -Each instance of a concrete subclass of CProtocolHandler is associated
    1.74 -with a specific	client session, and hence with a particular choice of proxy type,
    1.75 -and by implication, transport type.  It is designed to appear like a filter in
    1.76 -order to be placed at the end of a session's filter queue.  This allows it to 
    1.77 -receive transaction-related events in the same way that any other filter
    1.78 -(or indeed, the client) does.  An active object, it may implement a queuing
    1.79 -system for submitted transactions, according to the chosen internal service
    1.80 -model.
    1.81 -
    1.82 -In order to divide the abstract functionality associated with handling the HTTP
    1.83 -protocol handler from the specifics needed for a particular choice of transport,
    1.84 -this class defines a number of pure virtual methods which allow it to defer
    1.85 -transport-specific choices or mechamisms.  These are mainly concerned with the
    1.86 -service model (ie. allocation of transactions to objects that can handle them), the
    1.87 -codec model (ie. on-demand encoding/decoding of	HTTP header data) and general
    1.88 -housekeeping (eg. instantiation and cleanup of objects at particular points in
    1.89 -a transaction lifecycle).
