[Twisted-web] Listening on 2 addresses

[Axel Rau]

Hi Tom,

thanks for the explanation.  After adding some brackets, your example code works like a charm.

Using your pointers, I tried the next step: TLS.

This variant of the makeService method:

		ipv4_endpoint = endpoints.serverFromString(
			reactor, 'ssl:{}:privateKey={}:certKey={}:interface={}'.format(
				options['port'],
				endpoints.quoteStringArgument(options['cert_path']),
				endpoints.quoteStringArgument(options['key_path']),
				options['ipv4_address']))
		
		ipv6_endpoint = endpoints.serverFromString(
			reactor, 'ssl:{}:privateKey={}:certKey={}:interface={}'.format(
				options['port'],
				endpoints.quoteStringArgument(options['cert_path']),
				endpoints.quoteStringArgument(options['key_path']),
				options['ipv6_address']))
		
		ipv4 = internet.StreamServerEndpointService(ipv4_endpoint, meteo_factory)
		ipv6 = internet.StreamServerEndpointService(ipv6_endpoint, meteo_factory)
		
		root = MultiService()
		ipv4.setServiceParent(root)
		ipv6.setServiceParent(root)

does not work. It fails with:
	_parseSSL() got multiple values for argument ‚interface'
same with private privateKey and certKey.

What did I wrong this time?

Thanks, Axel
