Parked Domain blog directory not redirecting

[hfranz]

My newly parked domain name, (our main website had to switch primary domains) is not redirecting properly and is causing our blog to be duplicate content. My 301 redirects work for everything else, but our parked domain /blog directory is not redirecting. I can type in both urls and then the blog appears on both sites. Not good.

If I delete my blog .htaccess file, then it redirects fine. However, then our blog links are broken. So it has to do something with our .htaccess files. I do have a .htaccess file for our website, saying redirect everything to correct location, so i think this is interfering, but I cannot pinpoint it.

this is the .htaccess file for the blog.

BEGIN WordPress

<ifmodule mod_rewrite.c="">RewriteEngine On
RewriteBase /blog/
RewriteRule ^index.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /blog/index.php [L]</ifmodule>

END WordPress

main sites .htaccess (i am trying to pinpoint the issue here)

Options +Includes
AddType text/html .htm .html
AddHandler server-parsed .htm .html
Options +FollowSymLinks

RewriteEngine on

RewriteBase /

RewriteCond %{HTTP_HOST} ^(www.)?parkeddomain.com [NC,OR]

RewriteCond %{HTTP_HOST} ^newdomain.com [NC]

RewriteRule (.*) http://www.newdomain/$1 [R=301,L]

RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /([^?]*)?

RewriteRule (.*) /$1? [R=301,L]

RewriteCond %{THE_REQUEST} ^.*/index.php

RewriteRule ^(.*)index.php$ http://www.newdomain.com/$1 [R=301,L]

RewriteCond %{THE_REQUEST} ^.*/index.htm

RewriteRule ^(.*)index.htm$ http://www.newdomain/$1 [R=301,L]

RedirectMatch 301 /index.php/(.*) /$1

Is there something obvious here, that does not look right?

I'm not good with writing htaccess code, but just thought I would mention that if you don't get an answer, another solution would be to use a rel-canonical tag in the header, pointing to the domain you want indexed.  This would tell the search engines that the non-parked domain is the proper one to index.  The other one should drop out of the index after you do this.
