I'm having a bit of a play around with IIS7, just trying to catch events manually in global.asax and skip the ASP pipeline entirely. To this end, I've set

<httpHandlers>
    <clear/>
</httpHandlers>
<httpModules>
    <clear/>
</httpModules>   

but when I call the server I get a YSOD

[HttpException]: No http handler was found for request type 'GET'
   at System.Web.HttpApplication.MapHttpHandler(HttpContext context, String requestType, VirtualPath path, String pathTranslated, Boolean useAppConfig)
   at System.Web.HttpApplication.MapHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

What do I need to do to completely prevent IIS from handling things? What I want is just to do Response.Writes in event handlers and async methods set up in HttpApplication.Init
