Daphne is a HTTP, HTTP2 and WebSocket protocol server for

It supports automatic negotiation of protocols; there's no need for URL
prefixing to determine WebSocket endpoints versus HTTP endpoints.

If you intend to run daphne behind a proxy server you can use UNIX
sockets to communicate between the two::

want it to bind to a file descriptor passed down from a parent process.
To achieve this you can use the --fd flag::

from Let's Encrypt, which you can read more about at http://txacme.readthedocs.io/en/stable/.

Next, because all current browsers only support HTTP/2 when using TLS, you will
need to start Daphne with TLS turned on, which can be done using the Twisted endpoint syntax::

Alternatively, you can use the ``txacme`` endpoint syntax or anything else that
enables TLS under the hood.
