index.html has,
<html>
  <body>
    Main layout
    <link rel="import" href="a.html" />
  </body>
</html>
a.html has,
inner content!!!
When i open these pages using node-static, i see output as,
Main Layout
But i like to have,
Main Layout
inner content!!!
In summary, how to break my html file into seperate blocks & add/remove them on the fly??
