workers-leaktest

Test if Workers actually leaking queries when used to proxy against NextDNS.

• Create a new Workers using doh-cf-workers, set the upstream to your own NextDNS profile that includes the OISD list, with Block Page enabled in the setting.
• Install .NET 6 SDK
• Clone this project, change the proxydomain inside Program.cs with your own Worker address
• Run with dotnet run from the terminal

A normal run should only output All 400 succeeded (you can change testcount from 400 if you want, but a too large number might trigger Cloudflare/NextDNS DDoS protection), if you get a different result, open an issue.
