-> I was thinking that the global hack would only impact multiple
-> wsgi_intercept calls, which would be less of a problem. I believe you when
-> you say it's more than that, though, and I agree that doing it as middleware
-> is less hackish.
-> I'll need to play around with it a bit though, because right now the double
-> lambdas around app_fn are over my head. Should the middleware be added to
-> wsgi_intercept so that other potential users can use it?
You can replace the lambdas with a function that returns a WSGI
application object, suitably wrapped.
Ping me if you run into difficulties; it shouldn't take me very long to
whip something basic up.
