How to make a permanent redirection from http:// to http://www.?

Hi!

How to redirect every viewer of the site from http:// to http://www.?

The redirect should be permanent and it should include every file and every directory!

My current .htaccess looks like this:

IndexIgnore .htaccess */.??* *~ *# */HEADER* */README* */_vti*

<Limit GET POST>
order deny,allow
deny from all
allow from all
</Limit>
<Limit PUT DELETE>
order deny,allow
deny from all
</Limit>
AuthName mydomain.com

Code (markup):

I haven't modified it. The website uses CPanel.

Thanks!

 

Thanks for the tips. It's really work :3

 

Thanks for the answer, thewebhostingdir!

But before adding anything to my .htaccess I would like to know what's the actual difference between these two codes?

In the first one the redirection method is written with letters (R=permanent) but in the second one it's with numbers (R=301). Does it make a difference?

And why is there no $ in the end of the third string in the first code while there is in the second one? (^mydomain\.com vs. ^mydomain\.com$ [NC])

And what does the [NC] do?

Just wondering

Thanks!
