A error message generating the SiteMap

[Hypertexter]

No, I did not... it gave me no error, but bing.com describes another way:

Pinging Bing Using a HTTP request

If you have an automated system that generates your sitemap, you may find it easier to inform Bing about your sitemap by sending a HTTP request. Using your favorite method to send the request, use the following URL, replacing the example with your sitemap location and URL encoding everything behind the sitemap parameter:

http://www.bing.com/ping?sitemap=http%3A...itemap.xml

This is my code today: (Bing seems to be wrong)
