@Deprecated public abstract class AbstractClientConnAdapter extends Object implements ManagedClientConnection, org.apache.http.protocol.HttpContext
operated
to
managed
client connections.
Read and write methods are delegated to the wrapped connection.
Operations affecting the connection state have to be implemented
by derived classes. Operations for querying the connection state
are delegated to the wrapped connection if there is one, or
return a default value if there is none.
This adapter tracks the checkpoints for reusable communication states,
as indicated by markReusable
and queried by
isMarkedReusable
.
All send and receive operations will automatically clear the mark.
Connection release calls are delegated to the connection manager,
if there is one. abortConnection
will
clear the reusability mark first. The connection manager is
expected to tolerate multiple calls to the release method.

, the SSL session of

Note: Whether the underlying socket is an SSL socket
can not necessarily be determined via ManagedClientConnection.isSecure()
.
Plain sockets may be considered secure, for example if they are
connected to a known host in the same network segment.
On the other hand, SSL sockets may be considered insecure,
for example depending on the chosen cipher suite.
