Set home routes to direct in Sinatra simple authentication - ruby

Question

I'm trying to use Sinatra simple auth to force users to logon before being able to access the site. So the home page would be the logon then should be able to use the site without being prompted for it. At the moment I could not figure out a way to redirect to the home root page after logon. set :home is working as it should.

If what you want to do is check if a user is logged in before any routes except "/" you can use this:
before do
if request.path != "/"
if # statement which returns false if a user is logged in
redirect "/"
end
end
end
