/**
 * A kind of HostConfiguration that gets its Host from a factory. This is useful
 * for integrating a specialized Protocol or SocketFactory; for example, a
 * SecureSocketFactory that authenticates via SSL. Use
 * HttpClient.setHostConfiguration to install a HostConfigurationWithHostFactory
 * that contains the specialized HostFactory, Protocol or SocketFactory.
 * <p>
 * An alternative is to use Protocol.registerProtocol to register a specialized
 * Protocol. But that has drawbacks: it makes it hard to integrate modules (e.g.
 * web applications in a servlet container) with different strategies, because
 * they share the specialized Protocol (Protocol.PROTOCOLS is static). And it
 * can't support different Protocols for different hosts or ports (since the
 * host and port aren't parameters to Protocol.getProtocol).
