secureSocketTransport function
TLS over TCP — the transport to pass to AtLookUp.withSecureSocket unless
you are supplying your own.
A function rather than a constant because the configuration belongs to the
transport, and a caller has to state it: secureSocketTransport( SecureSocketConfig()) says "the TLS defaults", where a constant would let
a site inherit settings its neighbour set deliberately.
Implementation
AtLookupTransport secureSocketTransport(
SecureSocketConfig secureSocketConfig) =>
AtLookupTransport(
transportFactory: SecureSocketTransportFactory(
secureSocketConfig: secureSocketConfig));
