title: Angular 5 Multiple Service Worker in one domain
body: <p>I have two service workers  in two application on the same domain (both Angular 5):</p>
  
  <ul>
  <li>one inside /frontend/</li>
  <li>second inside /backend/</li>
  </ul>
  
  <p>I am using @angular/service-worker package to manage service worker.</p>
  
  <p>When i build prod version and deploy my applications something strange happens.</p>
  
  <p>When im enter first to <a href="http://my.domain/frontend/" rel="noreferrer">http://my.domain/frontend/</a> i can't go to <a href="http://my.domain/backend/" rel="noreferrer">http://my.domain/backend/</a> because service worker loading files and redirect me to <a href="http://my.domain/frontend/" rel="noreferrer">http://my.domain/frontend/</a></p>
  
  <p>What is wrong with this setup? i need to change file name of that service worker, or just i can't have two angular application on the same domain with this setup</p>
