David, Google returns a number of results on search of +"unknown status reply from server" +squid; i suspect the problem is there, and not rife-specific as Geert mentions.

Hi David, I can't think of any reason why RIFE should be the cause of this behavior since it totally relies on the underlying servlet functionality to actually communicate over HTTP.
