quantity property

int quantity

The number of different headers that you want CloudFront to base caching on for this cache behavior. You can configure each cache behavior in a web distribution to do one of the following:

• Forward all headers to your origin: Specify 1 for Quantity and * for Name.
• Forward a whitelist of headers you specify: Specify the number of headers that you want CloudFront to base caching on. Then specify the header names in Name elements. CloudFront caches your objects based on the values in the specified headers.
• Forward only the default headers: Specify 0 for Quantity and omit Items. In this configuration, CloudFront doesn't cache based on the values in the request headers.

Regardless of which option you choose, CloudFront forwards headers to your origin based on whether the origin is an S3 bucket or a custom origin. See the following documentation:

• S3 bucket: See HTTP Request Headers That CloudFront Removes or Updates
• Custom origin: See HTTP Request Headers and CloudFront Behavior
