# CacheTagConfigProperty

A complex type that specifies the HTTP header name from which CloudFront extracts cache tags from origin responses.

When you add ``CacheTagConfig`` to a distribution, CloudFront reads the specified header from origin responses, parses the comma-separated tag values, and stores them with the cached object. You can then invalidate cached objects by tag using the ``CreateInvalidation`` API.

## Example

```ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_cloudfront as cloudfront } from 'aws-cdk-lib';
const cacheTagConfigProperty: cloudfront.CfnDistribution.CacheTagConfigProperty = {
  headerName: 'headerName',
};
```

## Properties

- `headerName`: string (required) — The name of the HTTP header that your origin includes in responses.

  CloudFront uses this header to extract cache tags. The header value must contain comma-separated tag values (for example, ``product:electronics, category:tv, brand:example``).
