Multistore 302 Redirects

[moon-boots]

I noticed that every link on my site is being flagged up as a 302 temp redirect in Moz. The reason is because we have a multi store and use GeoIP to redirect anyone coming from their respective country.

I'm guessing a 302 is the wrong way to do this - can anyone shed advice on the best practice for redirecting customers to geo-specific stores?
