Handling OPTIONS request in nginx

I’m probably late, but I had the same problem, and found two solutions to it.

First is tricking Nginx that a 405 status is actually a 200 OK and then proxy_pass it to your HAProxy like this:

error_page 405 =200 @405;
location @405 {
    root /;
    proxy_pass http://yourproxy:8080;
}

The second solution is just to catch the OPTIONS request and build a response for those requests:

location / {
    if ($request_method = OPTIONS ) {
        add_header Content-Length 0;
        add_header Content-Type text/plain;
        return 200;
    }
}

Just choose which one suits you better.

I wrote this in a blog post where you can find more details.
