This makes sense. Conceptually I had considered it to be the
responsibility of the web client itself to handle the reconnection, not
the calling code, hence my plan for a subclass. But a separate class
which uses the Agent's API makes a lot more sense, and it can equally
provide the same interface as Agent so that any code which uses Agent
can use it without modifications.

Sounds like a plan! Thanks guys.
