Gets and sets the property DefaultRootObject. The object that you want CloudFront to return (for example, index.html) when an end user requests the root URL for your distribution (http://www.example.com) instead of an object in your distribution (http://www.example.com/index.html). Specifying a default root object avoids exposing the contents of your distribution. If you don't want to specify a default root object when you create a distribution, include an empty DefaultRootObject element. To delete the default root object from an existing distribution, update the distribution configuration and include an empty DefaultRootObject element. To replace the default root object, update the distribution configuration and specify the new object.

public string DefaultRootObject { get; set; }
