/**
|
|
* mod_qos.h: Quality of service module for Apache Web Server.
|
|
*
|
|
* The Apache Web Servers requires threads and processes to serve
|
|
* requests. Each TCP connection to the web server occupies one
|
|
* thread or process. Sometimes, a server gets too busy to serve
|
|
* every request due the lack of free processes or threads.
|
|
*
|
|
* This module implements control mechanisms that can provide
|
|
* different priority to different requests.
|
|
*
|
|
* See http://mod-qos.sourceforge.net/ for further
|
|
* details.
