That is exactly why you should not delete the references that application had to static pages. This page, "home.html" was a static web page in your website which is indexed on Google too. Deleting that page was a bad idea.
<title>My Web Page</title>
window.location = "http://www.abc.com/home/index";
This would do the job. Anyways, my other recommendation is to talk to your SEO team before asking for a new architectural design from your development team. :-)
