title: Angular-1 and Angular-4 Co-Existence in different Apps
body: <p>We're finding middle path between co-existence of Angular-1 and Angular-4 web applications by hosting them into separate virtual directories. </p>
  
  <blockquote>
    <p>The goal is- user should not feel any difference when they navigate
    across different routes.</p>
  </blockquote>
  
  <p>We have Angular-1 Application which has HTML-5 workers implemented. So we delegate file upload etc to background process. Web Workers.</p>
  
  <p>New enhancements we wish to do in Angular-4 with hyperlinks connecting old vs new apps.</p>
  
  <blockquote>
    <p>When control transfers to &amp; from from Angular-1 to Angular-4 app, Is there any
    workaround that background processes (Web workers), could be shared across two apps?</p>
