302 redirects??

My site is in the public_html folder and when using the www it redirects to the files in a www folder which is also in the public_html folder.

Oops, my fault.
It's in the root together with public_html.

I'm using this in the htaccess file in public_html:
RewriteCond %{HTTP_HOST} ^domain\.com
RewriteRule ^(.*)$ http://www.domain.com/$1 [R=301,L]

It works when using the adress without www but will this also work for search engines?

Do you know what that code does? It's giving a 301 redirect for all your pages. 301 is usually best used when you really need to redirect.

The domainname is http//domain.com but i can also use it with the www which is what most visitors use.

You need to check the DNS entries for your domain. Your name registrar may provide an interface for this. Make sure that your A record includes an alias www.domain.com as well as the straight domain.com (pointing to the same IP number)

There shouldn't be any need for a rewrite rule on the server, it should accept both domain.com and www.domain.com byy default.

<Files .htaccess>
Order allow,deny
deny from all
</Files>
RewriteEngine on
RewriteCond %{HTTP_HOST} !^.*domain\.com [NC]
RewriteRule (.*) http://www.domain.com/$1 [R=301,L]
RewriteCond %{HTTP_HOST} !^www.domain.com$ [NC]
RewriteRule ^(.*)$ http://www.domain.com/$1 [R=301,L]

The first being cravens rewrite to stop ip being identified!(hopefully correctly done by me)

tell me please Craven is the latter bad(or not smart) practise then?

RewriteCond %{HTTP_HOST} !^www.abc.def.com$ [NC]
RewriteRule ^(.*)$ http://www.abc.def.com/$1 [R=301,L]


Just to be clear when you have a moment

I thought the second way was just rewriting without the www.

If I am reading you right? this does also cover a IP address as well then?
and I can get rid of the initial rule
