Content items, search results, and groups can be accessed directly by a URL. For example, the URL http://www.arcgisonline.com/home/item.html?id=10189d5ffbce4ef48f5bcc0661cfaff9 opens to the World Imagery Map Service published by ESRI. Anybody can open the URL to a public item or group, including people who are not signed in to ArcGIS Online. Only group members can open the URL to a private group or to an item that's shared with that group, and only owners can open URLs to private items.
