===Unbind===
The Unbind operation abandons any outstanding operations and closes the connection.  It has no response.  The name is of historical origin, and is ''not'' the opposite of the Bind operation.<ref>[http://tools.ietf.org/html/rfc4511#section-4.3 Tools.ietf.org]</ref>

Clients can abort a session by simply closing the connection, but they should use Unbind.<ref>[http://tools.ietf.org/html/rfc4511#section-5.3 Tools.ietf.org]</ref> Unbind allows the server to gracefully close the connection and free resources that it would otherwise keep for some time until discovering the client had abandoned the connection. It also instructs the server to cancel operations that can be canceled, and to not send responses for operations that cannot be canceled.<ref>[http://tools.ietf.org/html/rfc4511#section-3.1 Tools.ietf.org]</ref>
