Mine

This is in one of my vhost config files.  What I'm trying to do with the lines delimited with #********** is make the Apache server itself handle an OPTIONS request, rather than forwarding it to the back end (a Mongrel cluster, using mod_proxy_balancer).

It works OK if I use the "main" server name for my apache:

#################################
$ telnet localhost 80
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
OPTIONS / HTTP/1.0
Host:localhost

HTTP/1.1 200 OK
Date: Thu, 02 Nov 2006 17:36:50 GMT
Server: Apache
Allow: GET,HEAD,POST,OPTIONS,TRACE
Content-Length: 0
Connection: close
Content-Type: text/html

Connection closed by foreign host.
#################################


It doesn't work if I use my vhost (using the config fragment below):

#################################
telnet localhost 80
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
OPTIONS / HTTP/1.0
Host:my-vhost-hostname

HTTP/1.1 400 Bad Request
Date: Thu, 02 Nov 2006 17:36:23 GMT
