title: send aiohttp post request with headers through proxy connection
body: <p>What I have now (Python 3.4):</p>
  
  <pre><code>r = yield from aiohttp.request('post', URL, params=None, data=values, headers=headers)
  </code></pre>
  
  <p>What is in the <a href="http://aiohttp.readthedocs.org/en/stable/client.html#proxy-support" rel="nofollow">documentation</a>:  </p>
  
  <pre><code>conn = aiohttp.ProxyConnector(proxy="http://some.proxy.com")
  r = await aiohttp.get('http://python.org', connector=conn)
  </code></pre>
  
  <p>So, how should I send a post request with headers through proxy connection with aiohttp?</p>
  
  <p>Thanks.</p>
