Apache Rewrite Rules for CentOS Grails Application with Tomcat - apache

Question

I am using Apache and Tomcat on a CentOS box and I want to do the following rewrites:
I want to handle abc.com to redirect to www.abc.com when a request is made.
I want to load my resources with Apache instead of Tomcat
This is my conf file. It is located in /etc/httpd/conf.d/tomcat.conf
#
# This configuration file enables the default "Welcome"
# page if there is no default index page present for
# the root URL. To disable the Welcome page, comment
# out all the lines below.
#
RewriteEngine on
RewriteRule ^/images/(.*) /images/$1
RewriteRule ^/css/(.*) /css/$1
RewriteRule ^/js/(.*) /js/$1
RewriteCond %{HTTP_HOST} ^abc\.com
RewriteRule ^(.*)$ http://www.abc.com$1 [R=301,L]
NameVirtualHost *:80
<VirtualHost *:80>
ProxyRequests Off
ProxyPreserveHost On
ProxyPass / ajp://127.0.0.1:8009/
ProxyPassReverse / ajp://127.0.0.1:8009/
ProxyPassReverseCookiePath / /
</VirtualHost>
My AJP proxy rewrite is working, I just need to do the following rewrites above.

apache redirect from non www to www
To load your resources with apache instead of tomcat, you can:
use apache mod_cache module, so you can decrease your tomcat load dramatically by caching your resources (css, js, images)
add servlet filters in your web application to set http cache headers in order to enable caching
