How to redirect non-www to www with .htaccess
Redirect help to improve your SEO ranking
 A Simple 301 Redirect
RewriteEngine On
Redirect 301 /oldpage.htm http://www.w3cgallery/newpage.php
Other way to redirect
RewriteEngine On
RewriteCond %{SERVER_PORT} !^443$ RewriteRule ^oldpage.html https://www.w3cgallery.com/newpage.html [R=301,L]
 You can use the same procedure above to redirect to another site, if we added the following to your .htaccess file on www.w3cgallery.com
 Redirect non-www to www
example: http://w3cgallery.com to http://www.w3cgallery.com
RewriteEngine On rewritecond %{http_host} ^w3cgallery.com [nc] rewriterule ^(.*)$ http://www.w3cgallery.com/$1 [r=301,nc]
Fortunately a small amount of code within your .htaccess file located at root can solve the canonical problem. What this code does is 301 redirect one form of the site to the other, it’s like you setup an unlimited number of the simple 301 redirects I listed earlier on the fly.
 Redirect non-www to www with index.html to domain name together
Its little hard to do, while you adding non-www to www and index.php to http://www.yourdomain.com/
must use this codes for this, if you use 2 above codes so it might stuck in redirection.
RewriteEngine On RewriteCond %{THE_REQUEST} ^[A-Z]{3,9} /index.html HTTP/ RewriteRule ^index.html$ http://%{HTTP_HOST}/ [R=301,L]
enjoy.
Warning: .htaccess/php.ini file can stop working your site if you use wrong code, USE ONLY AT YOUR OWN RISK!
