title: PuppeteerSharp requests to localhost?
body: <p>I am not exactly sure if that is a pure PuppeteerSharp question or if it belongs to puppeteer in general.</p>
  
  <p>I setup a browser with a page and request interception. When the browser navigates to an external webpage like google I subscribed the page request event and now I get some requests to localhost to different ports.
  I wrote a firewall with a whitelist on my own and I am asking myself do I have to allow those requests to localhost or not? I haven't noticed any difference. What's the difference when I blocked those or not?</p>
