The website has an auto-redirecting homepage on a multilingual site. Here is some background:

• User visits the site for first time > sent to javascript age verification page with country of origin selector. If selects "France" then served French page (.com/fr-fr/). If selects any other country, then served English page (.com/en-int/).

• A cookie is set, and next time the user visits the site, they are automatically served the appropriate language URL.

1st Question: .com/ essentially does not exist. It is being redirected to .com/en-int/ as this is the default page. Should this be a 301 redirect since I want this to serve as the new homepage?

2nd Question:. In the multilingual sitemap, should I still set .com/ as the hreflang="x-default" even though the user is automatically redirected to a language directory?

According to Google, as just released here: http://googlewebmastercentral.blogspot.com/2014/05/creating-right-homepage-for-your.html "automatically serve the appropriate HTML content to your users depending on their location and language settings. You will either do that by using server-side 302 redirects or by dynamically serving the right HTML content. Remember to use x-default rel-alternate-hreflang annotation on the homepage / generic page even if the latter is a redirect page that is not accessible directly for users."

So, this is where I am not clear.  If use a 302 redirect of .com/ to either .com/en-int/ or .com/fr-fr/, won't I then lose the inbound link value and DA/PA of .com/ if I just use a 302? Note: there is no .com/ at this moment.

Any advice is appreciated. Thanks,Alex
