IIS CORS Module support for Access-Control-Allow-Private-Network

Question

Chromium 98 introduces [1] a new CORS request. Is there a way to request support for additional CORS headers from the Official Microsoft IIS CORS module [2]? I've been through the configuration reference, and there did not seem to be a way to extend it to additional modules.

Hi @John Hoven ,

After testing, CORS module does not yet support this header now. So the solution is avoid using CORS module and set all response headers through custom headers of web.config.

<add name="Access-Control-Allow-Private-Network" value="true" />
