Conditional RSS Redirect with FeedBurner.com

Hello,

I am trying to redirect all the traffic on an RSS feed on my site to a FeedBurner feed. This is as per a help instruction on the FeedBurner site - http://www.google.com/support/feedburner/bin/answer.py?answer=78464&topic=13048.

The feed is found at mydomain/home/rss.xml. Therefore I have edited the htaccess file at ./home/.

Can anyone see anything wrong with this code?

# Various rewrite rules.
<IfModule mod_rewrite.c>
RewriteEngine on

# If your site can be accessed both with and without the 'www.' prefix, you
# can use one of the following settings to redirect users to your preferred
# URL, either WITH or WITHOUT the 'www.' prefix. Choose ONLY one option:
#
# To redirect all users to access the site WITH the 'www.' prefix,
# (http://example.com/... will be redirected to http://www.example.com/...)
# adapt and uncomment the following:
# RewriteCond %{HTTP_HOST} ^example\.com$ [NC]
# RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301]
#
# To redirect all users to access the site WITHOUT the 'www.' prefix,
# (http://www.example.com/... will be redirected to http://example.com/...)
# adapt and uncomment the following:
# RewriteCond %{HTTP_HOST} ^www\.example\.com$ [NC]
# RewriteRule ^(.*)$ http://example.com/$1 [L,R=301]

# Modify the RewriteBase if you are using Drupal in a subdirectory and
# the rewrite rules are not working properly.
#RewriteBase /drupal

# Rewrite old-style URLs of the form 'node.php?id=x'.
#RewriteCond %{REQUEST_FILENAME} !-f
#RewriteCond %{REQUEST_FILENAME} !-d
#RewriteCond %{QUERY_STRING} ^id=([^&]+)$
#RewriteRule node.php index.php?q=node/view/%1 [L]

# Rewrite old-style URLs of the form 'module.php?mod=x'.
#RewriteCond %{REQUEST_FILENAME} !-f
#RewriteCond %{REQUEST_FILENAME} !-d
#RewriteCond %{QUERY_STRING} ^mod=([^&]+)$
#RewriteRule module.php index.php?q=%1 [L]

# Rewrite current-style URLs of the form 'index.php?q=x'.
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]

RewriteCond %{HTTP_USER_AGENT} !FeedBurner
RewriteRule ^rss\.xml$ http://feeds2.feedburner.com/SonicCageDome-Latest [R,L]

</IfModule>

As you can see I have added the redirect to the end of the IfModule. But it is not redirecting still.
