By re-sending previously captured HTTP requests to your server(s), the way your browser does when you click, W3SimPack simulates an internet browser user, in order to automate human behavior.

W3Simpack provides a framework for: * Monitoring availability and performance of WEB applications, * Sending this kind of information to NAGIOS monitoring systems, * Performing stress tests on an WEB application and its servers.

W3Simpack is a package composed of three distinct modules: * A module designed to generate a scenario from a live WEB network capture, * A module designed to schedule such scenarios on given applications, and feeding NAGIOS with the results, * A module designed to perform stress tests on an application, by running many concurrent scenarios and recording response times and errors.

The central element of W3SimPack is the scenario which, once generated, can be replayed at will either by the provided scheduler or stress engine.
