Re: [Zope] correct 404 error page?

I was move or delete some subfolders from long running site, but _all_ search engines (google etc.) still does searching at these failed URLs for more than 2 months.

Does somebody have correct error message that these search engines will respect?

AFAIK, Google needs 301 Moved permanently. More info is on the google site. Most search engines also have some docs where described what they need to remove page from index.
