The pairing of this Processor with a HandleHttpRequest Processor provides the ability to use NiFi to visually construct a web server that can carry out any functionality that is available through the existing Processors. For example, one could construct a Web-based front end to an SFTP Server by constructing a flow such as:
HandleHttpRequest -> PutSFTP -> HandleHttpResponse
This Processor must be configured with the same <HTTP Context Map> service as the corresponding HandleHttpRequest Processor. Otherwise, all FlowFiles will be routed to the 'failure' relationship.
