-If the XMLHttpRequest or Fetch Ajax requests are sent to a different domain host, including subdomains, the correlation headers aren't included by default. To enable this feature, set the [`enableCorsCorrelation` configuration field](./javascript-sdk-configuration.md#sdk-configuration) to `true`. If you set `enableCorsCorrelation` to `true`, all XMLHttpRequest and Fetch Ajax requests include the correlation headers. As a result, if the application on the server that is being called doesn't support the `traceparent` header, the request might fail, depending on whether the browser / version can validate the request based on which headers the server accepts.

You can use the [`correlationHeaderExcludedDomains` configuration field](./javascript-sdk-configuration.md#sdk-configuration) to exclude the server's domain from cross-component correlation header injection. For example, you can use `correlationHeaderExcludedDomains: ['*.auth0.com']` to exclude correlation headers from requests sent to the Auth0 identity provider.
