Hi Runwan HTTP and HTTPS for synapse message mediation (_SynapseService) setting was there in the previous code (Proxy service only had the per service transports ) . I actually only did refractor - cut and paste and change only organization. Synapse as Handler module can be deployed without much effort... may three , four line ........
