Caching with Cloud CDN + API Gateway

[Princy]

Is there any clear documentation to implement caching with CDN + API Gateway?

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

<ResponseCache continueOnError="false" enabled="true" name="RC-Cache">

  <DisplayName>RC-Cache</DisplayName>

  <CacheKey>

    <Prefix/>

    <KeyFragment ref="request.uri" type="string"/>

  </CacheKey>

  <Scope>Exclusive</Scope>

  <ExpirySettings>

    <TimeoutInSeconds ref="">3600</TimeoutInSeconds>

  </ExpirySettings>

</ResponseCache>

I want to implement functionality similar to the above which is done in APIGEE. I want to know is there anyway to achieve this in API Gateway?
