Temporary vs Permanent Redirects in Web Mapping

Question:

Setting a redirect in Direct Web Service's Web Mapping causes the site to issue a 302 ("temporary redirect") status code. Search engines seeing a 302 may keep old URLs in their database, rather than updating to the new location.

Is there any way for Web Crossing to issue a 301 ("permanent redirect")?

Answer:

Yes. You can put a "permanent:" in front of the destination URL.

Example:

http://mysite.com/oldurl permanent:http://mysite.com/newurl
