Cross-Origin Resource Sharing Draft Published

The Web Applications Working Group has published a Working Draft of Cross-Origin Resource Sharing. User agents commonly apply same-origin restrictions to network requests. These restrictions prevent a client-side Web application running from one origin from obtaining data retrieved from another origin, and also limit unsafe HTTP requests that can be automatically launched toward destinations that differ from the running application's origin. In user agents that follow this pattern, network requests typically use ambient authentication and session management information, including HTTP authentication and cookie information. This specification extends this model in a number of ways.Learn more about the Rich Web Client Activity.
