Placing a landing page, pre-authentiation stage

Hi All,

First off, thank you to everyone who contributes on this forum, has helped my company create a fantastic scalable shiny app very easily …(and cheaply!).

I was wondering if anyone had experience placing a landing page with a login button, prior to the main authentication (we are using Auth0), where you can click Login and then it produces the login page and then ShinyProxy index page with the containers listed.

I understand that Nginx is redirecting to SP on first connecting and then SP serves up the authentication page. Is there a way to put a static HTML page between these two?
