Using multiple javascript service workers at the same domain but different folders : <p>My website offers an array of web apps for each client.  Each client has a different mix of apps that can be used.</p>

<p>Each web app is a hosted in a different folder.</p>

<p>So I need to cache for each client only it's allowed web apps instead of caching all the apps,  many of them  he the user, will not use at all.</p>

<p>I naively created a global service worker for the shell of the website and custom named service worker for each folder or app.  </p>

<p>However I noticed that after the first service worker, say sw_global.js service worker registers, installs, activates, fetches succesfully and creates a cache named cache-global,  the second service worker, say sw_app1,js,  which creates it's own cache cache-app1, clears all cache-global. </p>

<p>How can I use custom service worker for each folder?.  Please keep in mind that each folder is a microservice or a web app which is not necesarilly allowed for all users, so it's imperative to not cache all content from a unique service worker. </p>

<p>Actually I code on vanilla.js, no angular, no react, no vue, no nada.</p>
