Thanks Sean.

I'm just trying to get it as basic as I can so that it can be explained to
the customer.  There technical department wants 3 tiers and I need to make
sure that the model I put together complies to their standards.  I have no
idea what there standards are and I can't seem to find out so I'm covering
all bases.

The web server is basically a dumb piece of software that serves up 
HTML pages and images and passing any other requests to something that 
can handle it, e.g., passing .cfm/.cfc requests to an app server that 
runs CFMX.

The web server has .htm(l) / .gif / .jpg etc files.
The app server has .cfm / .cfc files.

If you ask for foo.cfm, the web server simply asks the app server to 
handle the request. CFMX runs the (local) foo.cfm page and passes the 
rendered output back to the web server which, in turn, passes it to the 
browser that requested it.

If you ask for foo.htm, the web server serves up that file. Same with 
foo.gif, foo.swf etc.

The web server doesn't really 'call' ColdFusion at all.
