#require serve ssl

Proper https client requires the built-in ssl from Python 2.6.

Disable the system configuration which may set stricter TLS requirements.

This test expects that legacy TLS versions are supported.

Make server certificates:

Our test cert is not signed by a trusted CA. It should fail to verify if

we are able to load CA certs.

Specifying a per-host certificate file that doesn't exist will abort.  The full

A malformed per-host certificate file will raise an error
