As the title says, I'd like to capture traffic only to particular subdomains. The docs give an example to allow all subdomains. But if say I wanted only to capture traffic for example.com/a, example.com/b and example.com/c, how would I do that? I've tried ^(?!example.com/(a|b|c)) (I've also tried escaping the forward slash), and, while it works in regex testers, mitmproxy has other ideas.
