Redirect index.html and index.php to Homepage of a website with .htaccess

1. Without www site domain was not forwarded to www
2. When I hit on Home page, it opened with /index.html extension

Although i have created a post for how to redirect non www domain to www and vice versa. so you can fixed problem number 1. where as for number 2 issue(/index.html extension problem), i will give you a code which you need to put in .htaccess file and upload it into the domain root. where as you can use canonical tag also which will help Google to know the original page but to remove this issue completely from your website you need to read this post.

Note : If you already have a .htaccess file uploaded to the server, just edit that and paste the below code  after the code present so that both the issues will be resolved through a single .htaccess file. If there is no .htaccess file just make a fresh file.
