Thanks, I was just reviewing this. The actual problem here is that the base URL should not be added to the log. Instead, the log should just store log data like JobKey/TriggerKey and then the log should be rendered as a string within a request, where the actual host/port is available.

Such a richer log would also make #10 possible.
