Description
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'])

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)
