Ive been using the following code..

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} !^www\.domainname\.com [NC]
RewriteRule ^(.*) http://www.domainname.com/$1 [L,R=301]

which redirects the domain from http://domainname.com to http://www.domainname.com to help in the search engines.. but anyway the problem is I've just registered another domain with a '-' in it.. like domain-name.com and i've tried using the same code..

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} !^www\.domain-name\.com [NC]
RewriteRule ^(.*) http://www.domain-name.com/$1 [L,R=301]

But it doesn't work.. so I quess it must be because of the '-'

So do I need to add something extra or make a change?

Thanks!

All I can think of is that the '-' is being interpreted as a character range delimeter (even though these normally need brackets round them).
Try escaping it with a backslash.

yeh thanks that solved it!

I thought that earlier but I must have used a forward slash instead by mistake so thats why i never worked!
