Application Initialization Module for IIS 7.5 issue

As a part of Proof of Concept utilizing the Application Initialization Module for IIS 7.5 to increase the speed of web apps initialization, I have created a simple web application hosted on IIS 7.5 (Windows Server 2008 R2) with SSL enabled. Please see global and local settings below.

If I understand correctly the way the Application Initialization Module works, I am expecting IIS to issue a request to appinit.aspx (https://localhost/alwaysrunning/appinit.aspx) to initialize the web application. This is however never happening.

Any ideas?

What is the purpose of the attribute initializationPage?

Any help with this would be greatly appreciated.

EDIT: When I disable SSL the Application Initialization Module issues a request to appinit.aspx as expected. I need to get this to work with SSL enabled though.

        </periodicRestart>
    </recycling>
    <processModel identityType="NetworkService" idleTimeout="00:00:00" />
</add>

<application path="/alwaysrunning" preloadEnabled="true" applicationPool="appinit">
    <virtualDirectory path="/" physicalPath="C:\inetpub\wwwroot\alwaysrunnig" />
</application>

Local settings in application's web.config file:
