Google indexing 301 as 302?

[optimierung]

We have a domain-1.tld1 which is redirected via 301 at the provider to www.domain-2.tld2.
We checked both http://www.domain-1.tld1 and http://domain-1.tld1 for the right redirect to target www.domain-2.tld2 using WebBug.

By chance we found a Google search result showing the wrong URL domain-1.tld1 but with the right content (www.domain-2.tld2).

It seems as Google is considering the 301 as a 302 in case of domain-1.tld1 (without www)

Anyone noticed this issue?

Thanks for your help

[edit reason] I de-linked the example URLs [/edit]

I have set such a redirect over a year ago, and still several thousand of the redirected URLs show in the SERPs.

There's something broken in their system.

Tedster, thanks

You believe this issue is not considered as a "strong DC problem" by Google?

Hi Friend,
If First URL is already indexed, and after redirection it will take time to remove from Google..
Some times both are indexed, So don't worry...
