Russell, Thanks for the reply.
Two reasons: 1) Up until now, I hadn't encountered a 404 that had triggered this particular process_exception. It hadn't occurred to me that since get_object_or_404 actually raises the Http404 exception that the behavior was going to be different than, say, a try block whose exception clause returned HttpResponseNotFound. 2) Once I had encountered this phenomenon, a quick google search led me to this page from the book: http://www.djangobook.com/en/beta/chapter16/ ....which seemed, at least for a moment, to verify my previous experience. I think though that I simply hadn't raised Http404 since implementing this middleware. It makes perfect sense that it behaves the way it does.
