cPanel redirect doesn't work!

Hi,
I used the feature in cPanel to redirect domain.com to www.domain.com. It palced the following code inside the .htaccess file:

RedirectMatch permanent ^/$ http://www.domain.com/

After this the site was unaccessible either with www or without. Only an alert says:

Redirect limit for this URL exceeded. Unable to load the requested page. This may be caused by cookies that are blocked.

Then tried wack0's FAQ:

Options +Indexes
Options +FollowSymlinks
RewriteEngine on
RewriteBase /
RewriteRule ^/(.*)$ http://www.domain.com/$1/ [R=301,L]

Still no redirects but able access both www. and doman.com.

Please advice what am I doing wrong here.

Thanks & Regards.

 

Maybe you want to use the inbuild cpanel redirect ?

 

RewriteEngine on
Options +Indexes
Options +FollowSymlinks
RewriteBase /
RewriteCond %{HTTP_HOST} !^www.DOMAIN\.com
RewriteRule (.*) http://www.DOMAIN.com/$1 [R=301,L]

 

Great many thanks w@Ckø!

Would you explain what this line actually do?

RewriteCond %{HTTP_HOST} !^www.DOMAIN\.com

Code (markup):

Read the OP please!

 

I'm guessing it says 'If www.DOMAIN.com with out www, do the next line.'
