---------------------------------------------------------
After thinking about this some more, I believe this can/should be done as a
single processor. In a single processor design, the processor opens a socket
and listens for incoming connections, routing requests as described in
HandleHttpRequest. However, the flowfile input queue for the processor is used
as the signaling mechanism coming from the backend. i.e. the input queue of
the same processor takes the place and responsibility of the HandleHttpResponse
processor.
In this design, there's no controller service to be configured nor two
processors that need to be added.

> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Reporter: Mark Payne
> Assignee: Mark Payne
>
> The idea here is that we can receipt an HTTP request and use NiFi, in essence
> to build a web server graphically. This opens up a wide range of
> possibilities, by allowing a DFM to easily add a web front-end to any service
> that NiFi can interact with or to perform any sort of action that NiFi has
> the ability to perform, such as data format conversion, etc.
> For example, if you want to provide a web-based front-end to an SFTP Server,
> you could do so by creating a flow like:
> ReceiveHTTPRequest -> PutSFTP -> RespondHTTPRequest
