I am interested to capture and log (on the server side) the referrer to my Dash app.
Naturally, checking the request object inside the callback is too late; the referrer is the page itself by then.
I notice that it is possible to override the client-side
dash-renderer and introduce hooks.
Is there a mechanism which can be used on the server side which could be used to introduce a hook when the initial layout is requested.
Thanks in advance for any hints/tips!
