mod rewrite not working

[ubonline]

I have a site with a blog in a separate folder, so there is mysite.com and mysite.com/blog.

I'm trying to have all pages go to www. For my main site it works fine. But for my blog it does not. So:

mysite.com redirects properly to www.mysite.com
mysite.com/blog/ stays at mysite.com/blog/ instead of www.mysite.com/blog/

Here is the htaccess code for my main site www.mysite.com:

<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?virtualpath=$1 [L]
</IfModule>

RewriteEngine on
RewriteCond %{HTTP_HOST} ^mysite\.com
RewriteRule ^(.*)$ http://www.mysite.com/$1 [R=301,L]


Here is the htaccess in blog directory www.mysite.com/blog/:

<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?virtualpath=$1 [L]
</IfModule>

Any suggestions?

Remove the .htaccess from ./blog. I don't see a reason to leave it there at all as its missing any rule indicating that a redirect to www. should exist, and the only rule it has is already within the root .htaccess.
Why is the second rule in the root .htaccess outside of the check for mod_rewrite.c? Put everything within the check for rewrite, except the second rewrite engine directive, you can just remove that.

Fou-Lu, that did it, thanks for the help!

Actually, that led all my individual blog pages to a page not found message, so I uploaded the htaccess back to the /blog and now it works. Thanks again.
