Images not returning with 304 response code due to rewrite module

In our ASP.NET web application, we use our own class to act as a rewrite module. It takes all requests to the server, acting as a bootstrapper.

To access an image on our web application, the browser requests domain.com/ResourceItem.aspx?Id=74

Does not having a proper URI mean the server will never respond with 304 NOT MODIFIED?

Does anyone have any ideas how to get the 304 response, so the browser doesn't have to download each image every refresh?
