HTTP balancer + NGINX/HHVM not working for some HTTP 1.1 methods

azk version: 0.16.3

Hello,

I found a weird bug, the azk HTTP balancer is not working with NGINX + HHVM for some HTTP 1.1 methods (like OPTIONS, PATCH).

I created a github repository with a README showing the tests which I did and a quick "how-to" replicate the tests: https://github.com/gabrielrcouto/azk-hhvm-bugs

Anyone have an idea about how to solve this problem or what is causing it?

Thank you very much,
Gabriel
