AEM 6.5 | Dispatcher Rewrite Rule

I have the below requirement:

Suppose when the end user enters http://abc-123.co.in , the rewrite rule should be set in such a way that the URL is internally expanded to its home page full URL say http://abc-123.co.in/en/home.html but the full URL should not be visible on the address bar to the end user but rather be seen as http://abc-123.co.in (with .html extension and repo structure upto 'home' removed). How do we set up a rewrite rule for this?

Similarily, when the end user clicks on say, http://abc-123.co.in/en/home/about-us.html from the home page, again the full URL should not be visible to the end user but rather be seen as http://abc-123.co.in/about-us (with .html extension and repo structure upto 'home' removed). How do we set up a rewrite rule for this?
