Custom host resolver

[BeyondDefinition]

Hi, I'm trying to use CEF on Windows to connect to a webserver on a local network that does not have a DNS server. The webserver requires connection by hostname, which I know up front. I don't have access rights to inject DNS into the system. I'd like to inject the hostname into my request from CEF.

I tried to:

• Wrap CefRequestContext (with CefRequestContext::GetGlobalContext() as wrapped instance) and provide a custom implementation for only ResolveHost.
  Result: Passing this instance to CreateBrowserSync does not trigger any calls to the wrapper request. Browser still works normally.
• Creating a CefRequest instance with CefRequest::Create() and trying to override the Host header with SetHeaderByName. Then loading the request with GetMainFrame()->LoadRequest(req).
  Result: The Host header in the request is not different then what was parsed from the URL
• Overriding CefRequestHandler and CefResourceRequestHandler. Then update the Host header with SetHeaderByName in OnBeforeResourceLoad.
  Result: OnBeforeResourceLoad is called, the Host header initially is not present in the header map and setting it does not have any effect.

I am running CEF Version: 87.1.6+g315d248+chromium-87.0.4280.66
How can I achieve this?

You can add an entry to the Windows HOSTS file.

Of course that would work, however we cannot assume (Windows 10) admin rights on the system that runs the browser.
I am looking for a solution that can work without admin rights.

There are many ways to set up DNS resolution on the local network. I suggest looking into one of those options.
