  org.apache.http.impl.nio.client.DefaultAsyncUserTokenHandler

All Implemented Interfaces:

org.apache.http.client.UserTokenHandler

@Contract(threading=IMMUTABLE)
public class DefaultAsyncUserTokenHandler
extends Object
implements org.apache.http.client.UserTokenHandler

Default implementation of UserTokenHandler for asynchrounous HTTP client communication. This class will use an instance of Principal as a state object for non-blocking HTTP connections, if it can be obtained from the given execution context. This helps ensure persistent connections created with a particular user identity within a particular security context can be reused by the same user only.

This implementation will use the user principle of connection based authentication schemes such as NTLM or that of the SSL session with the client authentication turned on. If both are unavailable, null token will be returned.
