Keep-alive and Safari

[doors]

I also founded NGIX disabled keep-alive for safari.

I am not sure exact reason of this.

### ngx_http_core_module.c
if (r->keepalive) {

            if (r->headers_in.msie6) {
                if (r->method == NGX_HTTP_POST) {
                    /*
                     * MSIE may wait for some time if an response for
                     * a POST request was sent over a keepalive
connection
                     */
                    r->keepalive = 0;
                }

            } else if (r->headers_in.safari) {
                /*
                 * Safari may send a POST request to a closed keepalive
                 * connection and stalls for some time
                 */
                r->keepalive = 0;
            }
        }
