I need to redirect users to our old website for browsers that can't handle Angular Material.
(1) I was thinking of detecting the browser agent and version, but I'm having trouble finding a definitive list for Chrome/Safari/Firefox of which browsers and versions actually work. Also the client detect code I tried didn't seem to return anything with iPhone 6/iOS9.
(2) Could I just detect a specific feature somehow, ie. flexbox, and use that to determine if the browser is unsupported?
