Is there a better way to replace online media resources with local files (other than using a custom scheme)?

[RadarNyan]

I'm currently rewriting an old project using CefSharp.WinForms. It's a simple browser that specializes in one thing: replacing online media resources with local files.

My old implementation was:

1. Match URLs in OnBeforeResourceLoad and modifying the scheme part request.Url before returning CefReturnValue.Continue
2. Handle the request from ResourceHandler of my custom scheme, basically creating an HTTP 200 / 206 response.
   This implementation results in a 307 redirect (as shown in developer tools) from the original URL (https://...) to my custom URL (myscheme://...)

The old code works, but I wonder if there's a better way to achieve this. For example, is it possible to return my forged response directly without having any redirects (all while not sending any traffic to the original URL)?
