      Currently, the documentation doesn't specify what should happen when the value for HTTP Header setting is empty. In the case above, the header with an empty value is added, despite the notice. Also, pure Legacy also adds the header with an empty value, but without the notice.

      Steps to reproduce

      1. Create new eZPublish installation (eZ Demo Site without the demo content)
      2. Add the following to the site.ini.append.php file:
        [HTTPHeaderSettings]
        CustomHeader=enabled
        Pragma[/]=
        
      3. Make sure the installation is running in the prod environment and that in your php.ini file you have error_reporting set to E_ALL and display_errors to On.
      4. Go to your-site.dev/content/view/full/2 . The notice pasted above will be displayed. Also, the response will have a "Pragma:" header with an empty value.
