Can you use data from the app inside the middleware?

For example for Google Analytics e-commerce tracking, you would need to provide the price of the current transaction value to the tracking pixel. Is it possible to access that information from inside the middleware?

Hi, I had not taken this kind of thing in to consideration - It's quite a specific case. As it's a middleware it doesn't have any proper interaction with the application, other than receiving the response.

Maybe it would be possible to place some kind of marker in the page response and parse this out before rendering - It seems kind of dirty to me.

I'm not sure of the exact life cycle of a middleware, is it initialized per request? Maybe the page could call instance methods on the current request instance to set properties, which the pixel rendering could use?

Can anyone else think of a better way?

I currently don't have the time to add this feature, but feel free to discuss and fork :)
