A client-side connection that relies on outside logic to connect sockets to the appropriate hosts.

A timeout while connecting to an HTTP server or waiting for an available connection from an HttpConnectionManager.
The lowest layer of connection handling is comprised of
The connection interface extends the core
by operations to set and update a socket. An operator encapsulates the logic to
open and layer sockets, typically using a
SocketFactory. The socket factory for
Scheme such as "http" or "https"
can be looked up in a
Applications without a need for sophisticated connection management can use
this layer directly.
On top of that lies the connection management layer. A
ClientConnectionManager internally manages
operated connections, but hands out instances of
This interface abstracts from the underlying socket operations and
provides convenient methods for opening and updating sockets in order
to establish a
The operator is encapsulated by the connection manager and called
Connections obtained from a manager have to be returned after use.
This can be

the connection, or by closing the
stream from which
that entity is being read.
Connection managers will try to keep returned connections alive in order to re-use them for subsequent requests along the same route. The managed connection interface and all triggers for connection release provide methods to enable or disable this behavior.
