  org.apache.http.impl.client.DefaultUserTokenHandler

All Implemented Interfaces:

UserTokenHandler

@Contract(threading=IMMUTABLE)
public class DefaultUserTokenHandler
extends Object
implements UserTokenHandler

Default implementation of UserTokenHandler. This class will use an instance of Principal as a state object for 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.

DefaultUserTokenHandler will use the user principal 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.

Since:

4.0
