Hello Peter, I believe you can catch the instance in a middleware class. I'm sure a better developer or someone on the core team can explain better than me.

I'm unsure of the logic behind the request handler class being returned in the request_finished and request_started signals, rather than the actual instance. I was wondering if some more enlightened developer could explain the logic behind such a decision - one of the lines of code in question is in core.handlers.wsgi line 246: signals.request_finished.send(sender=self.__class__) I'm pondering why the instance itself is not sent, as this would contain lots of pertinent information. I'm speculating it could be for a few reasons - to ensure that the handler is garbage collected after each request - if loads of pointers are floating about, then a badly written signal handler could cause some sort of memory leak? Or perhaps to avoid a signal handler mutating the request handler? Either way - it'd be useful to actually have the instance available - I'm interested to whether I guessed the reasons right? Thanks, Peter (I deliberated whether this was a django-users question, but as I'm more interested in the motivation of the decision rather than a fix, I figured this was the right place) No virus found in this incoming message.
