I'm running a site with a member area and some public accessible pages. The member area obviously requires users to authenticate, while the public pages are indexable by search engines.

Our global navigation includes links to the restricted pages. At the moment, when a user isn't logged in and accesses a restricted page, we're 302-redirecting them to a login page.

We have a lot of external links pointing to restricted pages (eg. profile pages), and since we're 302-redirecting the juice from these links are lost.

I've been thinking about changing the redirect from 302 to 301. How would this look from a search engines view? The pages aren't per se permanently moved - the current user just isn't authenticated to view the content of the page at the moment.

Would it be a problem that navigation contains multiple internal links that all 301 redirect to the same login page?

Any suggestions?

Thanks.
