In the above case, connection to serv1 will be encrypted by TLS. On

Dynamic hostname lookup
-----------------------
By default, nghttpx performs backend hostname lookup at start up, or
configuration reload, and keeps using them in its entire session. To
make nghttpx perform hostname lookup dynamically, use ``dns``
parameter in :option:`--backend` option, like so:
.. code-block:: text
backend=foo.example.com;;dns
nghttpx will cache resolved addresses for certain period of time. To
change this cache period, use :option:`--dns-cache-cache-timeout`.
Migration from nghttpx v1.8.0 or earlier
