How to make Chrome to proxy your localhost requests

Since 2018, the chromium engine implicitly bypasses localhost when proxying requests.

So to make it possible you should run chrome with --proxy-bypass-list=<-loopback> flag.

Working example: google-chrome --ignore-certificate-errors --proxy-bypass-list="<-loopback>" --proxy-server=http://localhost:8080. As a proxy you can use mitmproxy.
