Domain Frontig is one of the CDN services that can be used to bypass the filtering system. For example, what the GFW system sees is discord.com, but by using the host field, we set the main destination of the internet packets to our own server, and in this way, the filtering system is bypassed.

This feature has been disabled in Cloudflare CDN because malware used to exploit it, but other CDNs can be used for this purpose.
