Will redirecting a logged in user from a public page to an equivalent private page (not visible to google) impact SEO?

[bernienabo]

Hi,

We have public pages that can obviously be visited by our registered members. When they visit these public pages + they are logged in to our site, we want to redirect them to the equivalent (richer) page on the private site e.g. a logged in user visiting /public/contentA will be redirected to /private/contentA

Note: Our /public pages are indexed by Google whereas /private pages are excluded.

a) will this affect our SEO?

b) if not, is 302 the best http status code to use?

Cheers
