Flask request headers

[csheppard]

Long story short

After upgrading to aiohttp-1.0.1 and multidict-2.1.0 I can no longer get values from flask.request.headers.

Reverting back to aiohttp==0.22.5 multidict==1.2.2 works fine.

Expected behaviour

print(request.headers.get('Host'))
myhost.name

print(request.headers['host'])
myhost.name

Actual behaviour

print(request.headers.get('Host'))
None

print(request.headers['host'])
  <snip>
  File "venv/lib/python3.5/site-packages/werkzeug/datastructures.py", line 1312, in __getitem__
    return _unicodify_header_value(self.environ['HTTP_' + key])
KeyError: 'HTTP_HOST'

Steps to reproduce

Viewing the data of request.headers.dict['environ'] reveals that the key is actually 'HTTP_Host' and not 'HTTP_HOST' as werkzeug is looking for.

Your environment

aiohttp (1.0.1)
Flask (0.11.1)
gunicorn (19.6.0)
multidict (2.1.0)
Werkzeug (0.11.11)
