Interface HttpSocketPool

public interface HttpSocketPool

This interface represents a cache of idle sockets. Once a request has been handled, the now-idle socket can be remembered and reused later in case another HTTP request is made to the same remote host. Currently, the only instance of this interface is used by the HttpRequest class.
