The example for HttpApplication seems wrong example explaining IHttpModule

[jbennink]

The example given for HttpApplication seems wrong. The codes create an IHttpModule class that takes HttpApplication and used it but does not explain the capabilities of the HttpApplication class.

I would have expected a example explaining Application_Start here.
