A procedure that is called for every request handled by hyde serve. It needs to accept the following arguments:
- The requested page or #f if none was found for the requested path
- The requested path represented as a list of strings
- A thunk to be called in case no response was sent
The procedure should either send a response (e.g. via Spiffy's send-response procedure) or call the continue thunk. The default is serve-page.
Available since version 0.21.0.
