transferred much more efficiently.  This is also particularly true for SSL

But the separation makes it easier to put the application server on a box
that is not directly connected to the Internet.  Architecturally speaking,
this is a huge advantage since you don't generally want your application
code to be so vulnerable to attacks.  Using mod_jk, you can put Tomcat on a
