## Package org.apache.http.conn.routing Description

The client-side route representation and tracking API.

An `HttpRoute` is the path along which a request has to be sent to the server. The route starts at a local network address and may pass through one or more proxies before reaching the target. Routes through proxies can be tunnelled, and a layered protocol (TLS/SSL) might be put on top of the tunnel. The `RouteTracker` helps in tracking the steps for establishing a route, while an `HttpRouteDirector` determines the next step to take.

The `HttpRoutePlanner` is responsible for determining a route to a given target host. Implementations must know about proxies to use, and about exemptions for hosts that should be contacted directly without a proxy.
