# SingleWeightPolicyConfigProperty

Configure a policy that CloudFront uses to route requests to different origins or use different cache settings, based on the weight assigned to each option.

> This property is legacy. We recommend that you use [TrafficConfig](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-cloudfront-continuousdeploymentpolicy-trafficconfig.html) and specify the [SingleWeightConfig](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-cloudfront-continuousdeploymentpolicy-trafficconfig.html#cfn-cloudfront-continuousdeploymentpolicy-trafficconfig-singleweightconfig) property instead.
