jumbo1 on "WordPress htaccess overrides rewrite rule"

Hi All,

I'm having a problem with rewriting urls with wordpress.

I have my blog in a subdomain like: blog.domain.com
Whenever someone types domain.com/blog I want them to be redirected to blog.domain.com

I'm using the following in htaccess:
RewriteCond %{HTTP_HOST} ^domain.com$ [OR]
RewriteCond %{HTTP_HOST} ^www.domain.com$
RewriteRule ^blog(.*)$ http://blog.domain.com [R=301,L]

This code works if wordpress' default htaccess is removed, which is:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

If I keep this code however, url domain.com/blog doesn't get redirected, and I get a 404 page error.
But of course, removing the wordpress default htaccess breaks wordpress down.

Anyone has any solution to make it work?
