It also can be assigned to another port number between 1025 and 65535.
Websocket port: The Websocket enables two-way communications between browser-based
applications with servers that does not rely on opening multiple HTTP connections, in order to
avoid long polling. The protocol consists of an opening handshake followed by basic message
framing, layered over TCP. The protocol provides an alternative to HTTP polling from a web page
to a remote server.
For a management session across a firewall or router (over the Internet), it is necessary to
open a
Websocket port 888
on your router using the NAT traversal method for transferring
metadata for counting. The default Websocket port is also user configurable.
