iframe snippet fails under https
When you use flashproxy in an HTTPS iframe, you will get all kinds of Security-Related errors like "SecurityError" (IE) and "This operation is insecure" (Firefox). This seems to be caused by trying to establish an unenrypted (i.e. `insecure') Websocket under HTTPS.
Under Firefox this can be worked around by letting the user set
network.websocket.allowInsecureFromHTTPS, but there is no such thing for IE.
