Functions
void	coap_register_proxy_response_handler (coap_context_t *context, coap_proxy_response_handler_t handler)
	Registers a new message handler that is called whenever a response is received by the proxy logic.
int	coap_verify_proxy_scheme_supported (coap_uri_scheme_t scheme)
	Verify that the CoAP Scheme is supported for an ongoing proxy connection.
