At the core of a web server is a "listener" which can implement 
accepting incoming socket requests.

The "payload" can then be some standard action, or, a "script" to 
execute can be part of the payload.

Web servers usually are set up to perform some standard actions, and 
other actions will require a script for the desired action.  These 
scripts are what allows customization of a web server.  If very specific 
actions are required, that most likely will require a custom script.
