\brief The QHstsPolicy class specifies that a host supports HTTP Strict Transport
Security policy (HSTS).

\ingroup network

HSTS policy defines a period of time during which QNetworkAccessManager
should only access a host in a secure fashion. HSTS policy is defined by
RFC6797.
You can set expiry time and host name for this policy, and control whether it
applies to subdomains, either in the constructor or by calling setExpiry(),
setHost() and setIncludesSubdomains().
