Each ASP.NET application will create multiple instances of HttpApplication (Global.asax).
When a request is received it will be handed to one of the HttpApplication instances. The request will then stay with the same HttpApplication instance
for its lifetime. This means there is one HttpApplication instance per request being handled. Every HttpApplication instance
can, and will, be reused to handle many requests during its lifetime.
