Summary

Add a redirect to home page in the custom logout function when a user logs out of FHP

Background

In #227 / #242, @shraddhaag added a custom logout function to log the user out of the authentication provider service. However it was unclear at the time if the authentication endpoint for FAS accepts a next or redirectTo parameter. It would improve the overall user experience if the user was gracefully returned to the FHP home page when they log out of the app.

Details

There are one of two possible outcomes to resolve this:

1. Research more to see if FAS authentication endpoint accepts a redirect parameter
2. Implement something ourselves to handle redirects

Outcome

Better user experience when someone logs out of the web app, so they will be returned to the FHP home page
