When your sitemap is updated, these are the URLs to ping the search engines (replace [your sitemap web address] with your URL):

Google

http://www.google.com/webmasters/tools/ping?sitemap=[your sitemap web address]

Yahoo

http://search.yahooapis.com/SiteExplorerService/V1/updateNotification?appid=YahooDemo&url=[your sitemap web address]

MSN Live Search

http://webmaster.live.com/ping.aspx?siteMap=[your sitemap web address]

Ask

http://submissions.ask.com/ping?sitemap=[your sitemap web address]

moreover

http://api.moreover.com/ping?u=[your sitemap web address]

According to the sitemaps protocol, the URL to submit a sitemap to a search engine is supposed to be:

<searchengine_URL>/ping?sitemap=sitemap_url

but many search engines don't seem to actually accept ping submissions this way.
