Redirect na verzi domeny s www

Potreboval bych se zeptat, jakym zpusobem mam pouzit nasledujici rewrite pravidlo pro redirect na verzi domeny s www v mym htaccesu, kde uz jedno rewrite pravidlo mam (kvuli cistym URL).

Tohle rewrite pravidlo mam v htaccess (mezitim mam jeste spoustu jinych radku, ale ty jsou zakomentovany, takze snad neni treba je uvadet):

# Various rewrite rules.
<IfModule mod_rewrite.c>
RewriteEngine on

# If your site is running in a VirtualDocumentRoot at http://example.com/,
# uncomment the following line:
RewriteBase /

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]
</IfModule>


A Tohle pravidlo bych tam potreboval pridat (Jen nevim, jestli ho mam pouzit cely, nebo jen posledni dva radky? A kam presne ho mam umistit? Mozna je to jedno, ale jsem v tomhle naprosty laik, tak se radsi ptam, nez abych neco po...):

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



Dik za odpoved.

Takze treba tak?

# Various rewrite rules.
<IfModule mod_rewrite.c>
RewriteEngine on

# If your site is running in a VirtualDocumentRoot at http://example.com/,
# uncomment the following line:
RewriteBase /

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

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]
</IfModule>

Jo, to je jasny :) Diky. Vyzkousim to. Snad to pujde...
