title: Handling OPTIONS request in nginx
body: <p>We're using HAProxy as a load balancer at the moment, and it regularly makes requests to the downstream boxes to make sure they're alive using an OPTIONS request:</p>
  
  <blockquote>
    <p>OPTIONS /index.html HTTP/1.0</p>
  </blockquote>
  
  <p>I'm working with getting nginx set up as a reverse proxy with caching (using ncache).  For some reason, nginx is returning a 405 when an OPTIONS request comes in:</p>
  
  <blockquote>
    <p>192.168.1.10 - - [22/Oct/2008:16:36:21 -0700] "OPTIONS /index.html HTTP/1.0" 405 325 "-" "-" 192.168.1.10</p>
  </blockquote>
  
  <p>When hitting the downstream webserver directly, I get a proper 200 response.  My question is: how to you make nginx pass that response along to HAProxy, or, how can I set the response in the nginx.conf?</p>
