Yes, .getLocalAddress().getHostName() is not reliable. I don't assume the connection to be an HTTP connection. Probably I will set a new flag like allowPeep: true to request peeping into the header information if the users know that they are using HTTP for this connection. However, I'm afraid it's not possible to peep if the users are using HTTPS.
Thanks for the info, Enrico.
