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