▪ If the first specified proxy is reachable and the authentication is unsuccessful, your system doesn’t
try a different proxy path.
▪ The PAC file must contain pure JavaScript.
▪ Poly recommends your PAC files use the
.pac
or
.proxy
extension.
▪ Poly supports PAC JavaScript functions that return “
PROXY host:port
” and “
DIRECT
”. Poly
doesn’t support return values of “
SOCKS
”, “
HTTP host:port
”, or “
HTTPS host:port
”.
View Connections to the System
Access a list of current connections to your system.
The list provides the following information:
▪ Type of connection (for example, web)
▪ ID associated with the session (for example, admin or user)
▪ Remote address (IP addresses of the hosts accessing your system)
This list doesn’t show details related to sharing content. For example, if someone shares a video from an
HDMI-connected laptop, you don’t see that this device is connected to the system.
