Sitemap in robots.txt

Google and Yahoo allow a Sitemap: <sitemap_location> line in the robots.txt.

Do any of the other search engines use that feature?
Does it this feature help?

Might help the other search engines more. If you're already registed it with Google then Google will crawl it.

The xml sitemap shouldn't be linked to from the site, and so unviewable to normal users. So in theory, putting it in the .htaccess should be beneficial

Putting a sitemap in .htaccess is pointless. .htaccess file is intended as a set of directives to the Apache server.

All search engines read up and cache your robots.txt. They specifically look for information about prohibited links and directories.

why did i say .htaccess? i meant robots.txt

sorry

:D
