Apache mod_jk replacing mod_rewrite rules

Question

We have a slightly complex Apache 2.2 setup in front of a Tomcat 6.0 instance. The main Tomcat webapp is deployed in:

/opt/tomcat/webapps/ROOT

But we also have static content that we update semi-regularly. We didn't want to force a new build and deploy of the webapp, so that's stored separately in folders like:

/opt/tomcat/webapps/css
/opt/tomcat/webapps/foo
/opt/tomcat/webapps/bar

To handle this from Apache, we use mod_rewrite and rules look something like the following:

RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^/css/(.*)$ - [L]

RewriteCond ROOT/%{REQUEST_FILENAME} -f
RewriteRule ^/css/(.*)$ ROOT/$1 [L]

RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^(.*)\.(jpg|png|html|js)$ - [L]

RewriteCond ROOT/%{REQUEST_FILENAME} -f
RewriteRule ^(.*)\.(jpg|png|html|js)$ - [L]

RewriteRule ^/(.*)$ http://localhost:8080/$1 [P,L]
ProxyPassReverse / http://localhost:8080/

I now think I might want to start using mod_jk and I have two questions:

Is it even worth using mod_jk? I don't need load balancing.
Is it even possible to handle the cases I outlined where the static content is referenced as "http://www.example.com/css/foo.css", but we don't know if it's located in the Tomcat webapp or in one of the static folders.

Why do you think you might want to use mod_jk? Is what worth using mod_jk? — beans, Mar 03 '11 at 02:56

Why are you thinking of using mod_jk?

If it's to use ajp communication, to speed up transfer to tomcat why not look at mod_proxy_ajp?

You'd just change the tomcat rewriute rule to:-

RewriteRule ^/(.*)$ ajp://localhost:8080/$1 [P,L]

Good suggestion but it doesn't work if you are load balancing between 2 or more instances of JBoss since the AJP port needs to be balanced between servers. – djangofan May 09 '11 at 01:40
