Redirect subdomain to it's own domain

[JMZolezzi]

I know this has been asked plenty of times, but I can't seem to make it.

I'm using the following code extracted from one of one of jdMorgan's post to redirect blog.mydomain.com to www.domain-blog.com:

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

It's seems to work fine except for one small thing. The following redirectios happens:

• http://blog.mydomain.com -> [domain-blog.com...] --instead of being redirected to [domain-blog.com...]
  
• http://blog.mydomain.com/something -> [domain-blog.com...]
  

I'm placing the .htaccess at www.mydomain.com and I kept the following lines at the DNS zone of mydomain.com:

1. email A entry IP
   
2. www.email A entry IP
   

Where IP is replaced by the actual IP where both, mydomain.com and domain-blog.com are hosted.

Can anyone give me a hand of this please? Can't seem to do the right thing.

Your code is essentially correct. This results in the question: "Where is the code on this server that internally rewrites blog.mydomain.com to /blog"?

It's very likely that this code is present. The trick is to get your new redirect code to execute first.

If that's not possible, then the work-around is to put "^blog/" at the start of your RewriteRule pattern, outside of the parenthesized ".*" expression.
