so none of the other methods I tested distinguish between a standard `false` response, and a `false` response because the requested resource doesn't exist.  I think the fact that this method actually distinguishes between these is a fluke, so I'm not too worried about it.  If we think anyone will care, I think I'd rather update `parseBoolResponse()` to suppress the 404 response if the error message is an exact match to the string "Not Found", and return it otherwise.  But again, I don't think it's worth doing at this point.  What do you think?
