title: webpack-dev-server serve multiple html page with historyApiFallback
body: <p>I have a project build with angular 2 and webpack, and I would like to have two apps in this one single project.</p>
  
  <p>The problem is I can't figure out how to map different url to different entry point (HTML page) with "historyApiFallback".</p>
  
  <p>The project structure is as below:</p>
  
  <pre><code>front/
  --app.component.ts
  --main.ts
  --index.html
  admin/
  --app.component.ts
  --main.ts
  --index.html
  </code></pre>
  
  <p>the output result after bundle looks like this:</p>
  
  <pre><code>/dist
  --index.html
  --admin.html
  --index.app.js
  --admin.app.js
  </code></pre>
  
  <p>with only one app and historyApiFallback set to true, I can have "/hero/1", "/hero-list" or "/abc/def/ghi" point to index.html.</p>
  
  <p>What should I do so I can have everything starts with "/admin" eg: "/admin/edit-hero/1" points to admin.html, and every other url goes to index.html ??</p>
