# AWS::CloudFront::ContinuousDeploymentPolicy SessionStickinessConfig
<a name="aws-properties-cloudfront-continuousdeploymentpolicy-sessionstickinessconfig"></a>

Session stickiness provides the ability to define multiple requests from a single viewer as a single session. This prevents the potentially inconsistent experience of sending some of a given user's requests to your staging distribution, while others are sent to your primary distribution. Define the session duration using TTL values.

## Syntax
<a name="aws-properties-cloudfront-continuousdeploymentpolicy-sessionstickinessconfig-syntax"></a>

To declare this entity in your CloudFormation template, use the following syntax:

### JSON
<a name="aws-properties-cloudfront-continuousdeploymentpolicy-sessionstickinessconfig-syntax.json"></a>

```
{
  "[IdleTTL](#cfn-cloudfront-continuousdeploymentpolicy-sessionstickinessconfig-idlettl)" : Integer,
  "[MaximumTTL](#cfn-cloudfront-continuousdeploymentpolicy-sessionstickinessconfig-maximumttl)" : Integer
}
```

### YAML
<a name="aws-properties-cloudfront-continuousdeploymentpolicy-sessionstickinessconfig-syntax.yaml"></a>

```
  [IdleTTL](#cfn-cloudfront-continuousdeploymentpolicy-sessionstickinessconfig-idlettl): Integer
  [MaximumTTL](#cfn-cloudfront-continuousdeploymentpolicy-sessionstickinessconfig-maximumttl): Integer
```

## Properties
<a name="aws-properties-cloudfront-continuousdeploymentpolicy-sessionstickinessconfig-properties"></a>
