ManagedClientConnection

Obtains the current route of this connection.

Obtains the SSL session of the underlying connection, if any. If this connection is open, and the underlying socket is an SSLSocket, the SSL session of that socket is obtained. This is a potentially blocking operation.
Note: Whether the underlying socket is an SSL socket can not necessarily be determined via 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.

Returns the state object associated with this connection.

Indicates whether this connection is in a reusable communication state. See markReusable and unmarkReusable for details.

Indicates whether this connection is secure. The return value is well-defined only while the connection is open. It may change even while the connection is open.

Layers a new protocol on top of a tunnelled connection. This is typically used to create a TLS/SSL connection through a proxy. The route is the one previously passed to open. It is not guaranteed that the layered connection is secure.

Marks this connection as being in a reusable communication state. The checkpoints for reuseable communication states (in the absence of pipelining) are before sending a request and after receiving the response in it's entirety. The connection will automatically clear the checkpoint when used for communication. A call to this method indicates that the next checkpoint has been reached.
A reusable communication state is necessary but not sufficient for the connection to be reused. A route mismatch, the connection being closed, or other circumstances might prevent reuse.

Opens this connection according to the given route.

Sets the duration that this connection can remain idle before it is reused. The connection should not be used again if this time elapses. The idle duration must be reset after each request sent over this connection. The elapsed time starts counting when the connection is released, which is typically after the headers (and any response body, if present) is fully consumed.

Assigns a state object to this connection. Connection managers may make use of the connection state when allocating persistent connections.

Indicates that a tunnel to an intermediate proxy has been established. This is used exclusively for so-called proxy chains, where a request has to pass through multiple proxies before reaching the target. In that case, all proxies but the last need to be tunnelled when establishing the connection. Tunnelling of the last proxy to the target is optional and would be indicated via tunnelTarget(boolean, HttpParams).

Indicates that a tunnel to the target has been established. The route is the one previously passed to open. Subsequently, layerProtocol can be called to layer the TLS/SSL protocol on top of the tunnelled connection.
Note: In HttpClient 3, a call to the corresponding method would automatically trigger the layering of the TLS/SSL protocol. This is not the case anymore, you can establish a tunnel without layering a new protocol over the connection.

Marks this connection as not being in a reusable state. This can be used immediately before releasing this connection to prevent it's reuse. Reasons for preventing reuse include error conditions and the evaluation of a reuse strategy.
Note: It is not necessary to call here before writing to or reading from this connection. Communication attempts will automatically unmark the state as non-reusable. It can then be switched back using markReusable.
