Notes

  • Logo: We recommend you to save and use our logo on your own web server. In that way there will not be any contact with our web server when your website is visited.
  • Content-Security-Policy (CSP): In case you are using a CSP policy for your website you would also need to add internet.nl to the rules for form-action and possibly also for img-src in case you link to the logo on our web server.
