Redirecting ISAPI app

[TinyCthulu]

I had no problem with deploying app on IIS, as long as I'm connecting to "http://#.#.#.#/virtualdir/app.dll", application works.

How to configure IIS to call my app as "http://#.#.#.#/alias" ?

I followed instruction provided by atozed:  http://docs.atozed.com/docs.dll/deployme...20IIS.html  but without success.
I made required changes to ServerController.OnConfig() 

All I get is error:
