Django: app level variables

by

A possible solution is to implement a custom Django middleware, as described in https://docs.djangoproject.com/ja/1.9/topics/http/middleware/.

You could initialize the HTTP connection pool in the middleware’s __init__ method, which is only called once at the first request. Then, start the HTTP request during process_request and on process_response check it has finished (or wait for it) and append that response to the internal one.
