Welcome to WebmasterWorld Guest from 18.104.22.168
On October 1st, 2010, we will drop the beta designation from the Bing crawler and change the name of the crawler to reflect Microsoft's new brand for search. Instead of the old msnbot 2.0b showing up in your server logs, the updated user agent will be:
Mozilla/5.0 (compatible; bingbot/2.0 +http://www.bing.com/bingbot.htm)
The HTTP header From field will also change as shown below:
We want webmasters to know that bingbot will still honor robots.txt directives written for msnbot, so no change is required to your robots.txt file(s).
