Can't accept more than one connection header

[Eden Li]

I'm setting nginx up behind a proxy which sends two Connection
headers, one for transfer encoding and one for keep-alive. So:

       Connection: TE
       Connection: keep-alive

causes nginx to return a 400 error.  Is there any way to fix nginx to
obey both headers rather than rejecting the request?

$ curl -H 'Connection: keep-alive' -H 'Connection: TE' -v http://yyy/
* About to connect() to 10.16.1.19 port 80 (#0)
*   Trying 111.111.111.111... connected
* Connected to 111.111.111.111 (111.111.111.111) port 80 (#0)
