I created an app like in the tutorial and started Django. When I issue
successive requests, the session gets disconnected. Here is an example:
{{{
>>> s = requests.Session()
>>> s.get('http://localhost:8000/'); s.get('http://localhost:8000')
<Response [404]>

During handling of the above exception, another exception occurred:
Traceback (most recent call last):

}}}
It I have a small timeout between the requests it works fine:
{{{
>>> s = requests.Session()
>>> s.get('http://localhost:8000/'); time.sleep(1);
s.get('http://localhost:8000')
<Response [404]>
<Response [404]>
}}}
It also works fine if I don't use sessions:
{{{
>>> requests.get('http://localhost:8000/');
requests.get('http://localhost:8000')
<Response [404]>
<Response [404]>
}}}
I initially reported this as a bug in the `requests` library but it does
not appear to be the case. See discussion here
