With Burp Suite we can capture the traffic of protocols like http, https. But i want now monitor the data traffic in urls like chrome://settings
chrome:// is not a protocol like HTTP or HTTPS. It's a scheme handled internally by chrome to display internal pages, such as your settings or your installed extensions.
Chrome does not fetch what the settings look like from some external source. It's built into the application. This is easily verifiable by opening
chrome://settings on a machine with no network access.
If these internal sites require external data, regular HTTP or HTTPS requests are sent.
