getID
public String getID()(Code)
Returns a String identifying the authentication challenge. This is used, in combination with the host and port to determine if authorization has already been attempted or not. Schemes which require multiple requests to complete the authentication should return a different value for each stage in the request.

Additionally, the ID should take into account any changes to the authentication challenge and return a different value when appropriate. For example when the realm changes in basic authentication it should be considered a different authentication attempt and a different value should be returned.

String a String identifying the authentication challenge. Thereturned value may be null.



getParameter
public String getParameter(String name)(Code)
