Handler
A handler that doesn't hand-off an exchange to another handler downstream is responsible for creating the response in the exchange object.
Important note: If an existing response exists in the exchange object
and the handler intends to replace it with its own, it must first check to see if the
existing response has an entity, and if it does, must call its close
method in
order to signal that the processing of the response from a remote server is complete.
exchange
- the exchange containing the request to handle.HandlerException
- if an exception occurs that prevents handling of the request.IOException
- if an I/O exception occurs.Copyright © 2014 ForgeRock AS. All rights reserved.
