ASP.NET

I've got an application where a shared object needs a reference to a per-request object.

Shared:      Engine
                |
Per Req:  IExtensions()
                |
             Request

If i try to inject the IExtensions directly into the constructor of Engine, even as Lazy(Of IExtension), I get a "No scope matching [Request] is visible from the scope in which the instance was requested." exception when it tries to instantiate each IExtension.

How can I create a HttpRequestScoped instance and then inject it into a shared instance?

Would it be considered good practice to set it in the Request's factory (and therefore inject Engine into RequestFactory)?
