Ok, I am an idiot who does not RTFM… Sorry

```elixir
socket "/live", MyAppWeb.UserSocket,
  websocket: [connect_info: [session: { __MODULE__ , :runtime_opts, []}]]

# ...

def runtime_opts() do
  Keyword.put(@session_options, :domain, host())
end

```

However, this will not allow me to access the `conn` object, which I need in order to determine the correct domain name.
