If you are using Akamai as your CDN, then you can configure NEL through Akamai by following the below steps:

  1. Log in to Akamai Luna Center
  2. Select the property which contains configurations related to your domain from the Property Manager.
  3. Edit the current production version to create a new version.
  4. Include rule: Modify Outgoing Response Header and add values as shown below AKK1.png

Headers and values:

Report-To: {"group":"network-errors", "max_age":2592000,"endpoints":[{"url":"https://r.3gl.net/hawklogserver/<app id>/re.p"}]}

NEL: {"report_to":"network-errors", "max_age":2592000, "success_fraction":0, "failure_fraction":1.0, "include_subdomains":true}

You can choose to apply these headers for specific sites or pages in a site by using the match condition as shown below: AKK2.png

  1. Save changes and activate the configuration in the staging environment.
  2. After testing, deploy changes in the production environment.
