Capturing localhost traffic

[Eonasdan]

I've used the Basic, WPF and a new console app following the readme. I don't see any traffic from localhost. I'm developing a web app and I'd like to be able to capture and log api calls from my angular -> api.

Localhost traffic is tricky ? most browsers bypass the system proxy for localhost / 127.0.0.1 on purpose.

Workarounds:

1. Hit your app via the machine name / LAN IP instead of localhost (e.g. http://192.168.x.x:4200).
2. Chrome: launch with --proxy-server=127.0.0.1:8000 and use a hostname that isn't in the bypass list. You can also try http://local.mydomain mapped in hosts.
3. Firefox: set network.proxy.allow_hijacking_localhost to true in about:config.
4. Don't rely on SetAsSystemProxy alone for loopback ? configure the client explicitly.

Also make sure Angular/HttpClient isn't talking straight to the API without going through the browser proxy settings.

Closing ? reopen if a specific browser still skips the proxy after the above.
