  • To integate a CDN service on https:// website you can use https://12345.r.cdnsun.net or you can use a custom CDN domain with SSL enabled.
  • If your website embeds custom fonts then please first enable CORS for them.
  • Before you take any steps please make sure that your CDN domain is ready-to-use here.
