You have created a Web application using a JBoss application server and you are going to put it in production. Great!
But deploying your application with JBoss serving the Web requests directly may not be the optimal solution. First because the Tomcat web server embedded within JBoss is not the best server to serve static files and second because configuring Tomcat and JBoss for best performance and security is in general a complex and tedious task.
Instead, it is a good practice to use an Apache server (2.0 or 2.2) in front of your JBoss/Tomcat. This Apache server can serve static files, take care of your SSL security and manage for you all the details of HTTP headers (Expires and other headers) and more....
