lighttpd forum lighty > FastCGI can't set response status code from 1.4.x?

I have a FastCGI app that needs to send a 403 under some circumstances.
In lighttpd 1.5.x, this works, but the same code under lighttpd 1.4.19
always returns 200. I can't deploy 1.5.x in my production environment
yet. Is there a workaround or fix planned for 1.4.x?
