Lighttpd

Hi, I'm developing the FastCGI ASP.NET server for Mono and I've come into a problem. When serving a static file, the ASP.NET responds with the following:

--
HTTP/1.1 304 Not Modified
Date: Wed, 08 Aug 2007 10:25:33 GMT
Content-Length: 0
Cache-Control: private
Content-Type: text/html; charset=utf-8
--

However, WireShark is telling me that the actual response from the server is "HTTP/1.1 200 OK ...", so images, CSS, etc become a blank page every other refresh. Lighttpd should use the status code provided by the server response, as 300 level response give instructions to the client.
