To echo Marvin Smit's comment, it seems that configuring under a in web.config simply does not work - any modules specified in this fashion are NOT invoked.

What you can do is to specify the module at root level, and have it controlled by an appSetting, which can be hierarchically specified and overridden as required:

Then within the code for CustomModule:

    private static bool ModuleEnabled()
    {
        bool appSetting;
        if (!bool.TryParse(ConfigurationManager.AppSettings["UseCustomModule"], 
                           out appSetting))
            appSetting = false;

        return appSetting;
    }

ASP.NET will see to it that the appropriate value of UseCustomModule for our current location is the one we read.
