When developing Phillips HUE apps, developers use the clip website on the HUE hub, for example
http://192.168.1.3/debug/clip.html. Responses from this website do NOT return a "Content-Length" header, but instead returns a "connection: close" header. Apparently Web Shield is waiting for the content length header to determine whether the request has finished to analyze the received data....which consequently hangs the request and never allows the stream back to the browser for display. Eventually, the browser just times out. I've tried adding a website exception for "192.168.1.*", but that doesn't make any difference.
