Enable Cross-Origin Resource Sharing (CORS)

Most modern browsers implement the Same-Origin Policy, which restricts how a document or a script loaded from one origin can interact with a resource from another origin. When the Enable cross-origin resource sharing property is enabled on Cloudera Machine Learning, web servers will include the Access-Control-Allow-Origin: * HTTP header in their HTTP responses. This gives web applications on different domains permission to access the Cloudera Data Science Workbench API through browsers.

This property is enabled by default .

If this property is disabled, web applications from different domains will not be able to programmatically communicate with the Cloudera Data Science Workbench API through browsers.
