Lighttpd

I have setup lighttpd with mod_proxy to redirect requests to /msg/* to 127.0.0.1:8888/msg/* which works fine for GET requests.
When sending a post request the client gets no response from the server (the request is send to the backend-server, but the response is not passed through)

config:

server.modules   += ( "mod_proxy" )
proxy.debug = 1
proxy.balance     = "fair" 
$HTTP["host"] == "im.xxx.de" {
$HTTP["url"] =~ "^/msg/" {
proxy.server     = ( "" =>
                     (
                       ( "host" => "127.0.0.1",
                         "port" => 8888
                       )
                     )
                    )
}
}
