Forcing Subdomain Redirect With htaccess

I just happened to do a search for my site, recordingreview.com, in Google and I noticed that I had two entries for my forum (which is on a subdomain).

www.recordingreview.com/forum/

and

forum.recordingreview.com/ both appeared.

This is bad news for duplicated content! So, I immediately hopped on a few forums but none of them seamed to know the answer. I was also concerned that I would mess something up in vBSEO.

So here is the solution to force a subdomain to ONLY go to the subdomain.

Note:

  • This htaccess MUST be in the folder you want to redirect from.
  • This will only be necessary on servers that allow you to access the subdomain by typing in domain.com/subdomain/

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