Apache Rewrite Rules for CentOS Grails Application with Tomcat

Question

I am using Apache and Tomcat on a CentOS box and I want to do the following rewrites:

1. I want to handle abc.com to redirect to www.abc.com when a request is made.
2. 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.

Answer 1

1. apache redirect from non www to www
2. 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
