I have code that redirects visitor to login -page via authentication provider selector -page
site.com/ -> 302
site.com/check-authentication-providers.aspx -> 301
site.com/login.aspx
Positive thing of course is to have code separated clearly by having separate pages but are there negative impacts on this model?
