Redirect parked domain to primary domain

How can I redirect my parked domain to my primary domain instead of having the parked domain act as an unstable primary domain? Example: parkeddomain.com should redirect to domain.com
Will this interfere with vBSEO?

Hello,

you can setup a www/non-www 301 redirect as described in [How to] Setup www.yourdomain.com or yourdomain.com (www vs. non-www) - With .htaccess 301 redirects and that should redirect all parked domains as well.

And if I'm using the htaccess for the purpose in the topic you linked to and to redirect the parked domain, would it look the code in the code box below?

By the way, regarding that topic, can I do both? use htaccess and webmastertools for the www or non www thing?

Code:

 RewriteCond %{HTTP_HOST} ^www\.wc3sear\.ch$ [AND] 
^www\.blizzard\.cd$
RewriteRule ^(.*)$ http://www.blizzard.cd/$1 [L,R=301]

You should use this code:

Code:

RewriteCond %{HTTP_HOST} !^www\.blizzard\.cd$
RewriteRule ^(.*)$ http://www.blizzard.cd/$1 [L,R=301]

The parked domain is wc3sear.ch and the primary is blizzard.cd
I was also asking about that thread your partner linked me to and was wondering whether it would help to use both methods ( google webtools and htaccess ).

The code above will redirect request to ANY domains that is NOT "www.blizzard.cd", i.e. "blizzard.cd", "wc3sear.ch", "www.wc3sear.ch" or anything else.

Okay, I'll try it. Thanks. Should I set my URL as Blizzard Citadel in vbulletin options or should I skip the www? ( I want it to be www. but I'm not sure if it's allowed in admincp. ) And will this do or should I also set preferred URL in Google webmaster tools?

Thanks.

Set it to whichever version you want to used exclusively. If you already have pages indexed with "www" you might as well keep using that.

I know, I was trying to ask whether I should also add the preferred domain in Google Webmaster Tools or is it enough to put it in the htaccess file?

You should definitely specify it in Google Webmaster Tools as well.
