Our search engine contains snapshots of the majority of pages discovered during the crawl of the Web. We link to the cached page so the user can click it if the original site's server is down. When you view a cached page you see it as it looked when Yahoo! Slurp last crawled it, with search terms highlighted.
If you do not want your content to be accessible through the cache link, you can use either of these methods to instruct robots not to archive the page:
<META NAME="ROBOTS" CONTENT="NOARCHIVE">or
X-Robots-Tag: NOARCHIVEOur crawler continues to index and follow links from the page, but it does not display a cached page link in search results. Please note this change occurs the next time the search engine crawls the page containing the NOARCHIVE tag or directive (typically at least once per month).
Important: NOARCHIVE only removes the cached page. To prevent the page content from being indexed, use the NOINDEX tag. To prevent the crawler from following links, use the NOFOLLOW tag.
