WebResource filter with custom host

[valapran-flutterint]

I am trying to filter request with a custom host, https://cst_host/page. Then I will use add_WebResourceRequested to provide custom response. I want to use https protocol here but with a custom host. Don,t/Can't want to use custom scheme.

CEF had CefRegisterSchemeHandlerFactory where I can specify a host as well, do we have similar in WebView2?

Everything works fine, but the issue is that I get DNS timeout and the total turnaround for the request takes 2+ seconds because of this. How to bypass the dns part here?
