SPA Security Enforcer

Hi,

I have started with a fresh new ASP .NET application and I am setting it up as an SPA.
Have done this part before as well, so all is working fine here.
Along with this, was trying to confiugure the new option to set security provider enforcer on content pages.
But, I am not sure as to what to put in the redirection URL

EDIT: I was able to get it to work by selecting the CONTENT page in the inputs. Now I am redirected to the login page, but the URL still shows the secure page. And after login, I no longer get redirected to the secure page.
