[Twisted-web] Listening on 2 addresses

[Tom Most]

Hi Axel,

I'm not entirely sure what's going wrong there (maybe quote the ipv6 address?), but you want to retain the various independent command-line options you should instantiate endpoints directly rather than constructing an endpoint string (the endpoint string is useful to expose *directly* as a CLI parameter).

I.e., you can construct SSL4ServerEndpoint <https://twistedmatrix.com/documents/current/api/twisted.internet.endpoints.SSL4ServerEndpoint.html> directly. Oddly SSL6ServerEndpoint doesn't exist, though, and I don't see a generic server wrapper like wrapClientTLS <https://twistedmatrix.com/documents/current/api/twisted.internet.endpoints.html#wrapClientTLS> for the server site. I'm afraid I may have led you down the wrong path --- I didn't realize this was missing.
