am having this issue with a lighttpd reverse proxyed forum and my blog
(index):1 XMLHttpRequest cannot load http://forum.domain.com/comments/get/114/0. The 'Access-Control-Allow-Origin' header contains multiple values ', undefined', but only one is allowed. Origin 'http://domain.com' is therefore not allowed access.
lighttpd conf
$HTTP["host"] == "forum.domain.com" { proxy.server = ( "" => ( ( "host" => "127.0.0.1", "port" => "4567" ) ) ) }
