title: Global JavaScript Listener to block specific URL curl from background/child process
body: <p>I have a JavaScript embedded in HTML using a sdk.js
  This SDK is using a compiled <em>wasm</em> file (not possible to decompile it), that child is performing a curl to a specific domain.</p>
  <p>I am looking for a solution to include a global URL listener in my HTML JavaScript
  in order to block the curl to that specific domain.</p>
  <p>Is this somehow possible? Does anybody has a clever idea to solve that issue?</p>
