HP WebQoS Peak for HP-UX Concepts and Operation Guide

Chapter 2 17
Overview
What is HP WebQoS Peak?
How Does HP WebQoS Work?
HP WebQoS monitors the resources and the number of arriving sessions
on the web server. Based on available resources and how HP WebQoS is
configured, it will accept, defer, reject or redirect a session. HP WebQoS
makes sure the web server does not become overloaded by deferring,
rejecting or redirecting any new sessions for which it does not have
resources. It also allows an admitted session to be completed.
When the web server’s resources are available, HP WebQoS allows the
session to begin and will fulfill all requests made during this session. HP
WebQoS monitors the time between requests as well as the length of the
session. If one of these variables exceeds the thresholds configured in HP
WebQoS, the session is terminated. Otherwise, all requests are fulfilled
until the session is completed.
When the web server’s resources are not available, HP WebQoS will
defer, reject or redirect the session. The web administrator can choose to
redirect the request to another URL, or serve a page with an error
message or some helpful information.
