// This test connects to ocsp-stapling-none.example.com to test that OCSP
// requests are cancelled if they're taking too long.
// ocsp-stapling-none.example.com doesn't staple an OCSP response, so
// connecting to it will cause a request to the OCSP responder. As with all of
// these tests, the OCSP AIA (i.e. the url of the responder) in the certificate
// is http://localhost:8888. Since this test opens a TCP socket listening on
// port 8888 that just accepts connections and then ignores them (with
// connect/read/write timeouts of 30 seconds), the OCSP requests should cancel
// themselves. When OCSP hard-fail is enabled, connections will be terminated.
// Otherwise, they will succeed.
