Port websocket

Nov 1, 2017 The client establishes a WebSocket connection through a process as to HTTP style URLs. ws is unencrypted and has port 80 as default,

In some situations WebSocket connections are blocked over port 80. In this case a secure SSL connection using WSS over port 443 should successfully connect. The WebSocket protocol, described in the specification RFC 6455 provides a way to exchange data between browser and server via a persistent connection. The data can be passed in both directions as “packets”, without breaking the connection and additional HTTP-requests. A WebSocket is a standard bidirectional TCP socket between the client and the server. The socket starts out as a HTTP connection and then "Upgrades" to a TCP socket after a HTTP handshake.

So, using WebSocket is a trade-off between saving crucial bytes and enabling faster conversations at the cost of blocking a port for longer. The best use-case of WebSocket is when you need real-time data really quick, like stock prices. Stock prices change every second. WebSocket connections generally work even if a proxy or firewall is in place. This is because they use ports 80 and 443 which are also used by HTTP connections. In some situations WebSocket connections are blocked over port 80. In this case a secure SSL connection using WSS over port 443 should successfully connect.

Over and above, this server can also be used for easily overriding the default settings with your custom ones, e.g. changing the listeners' port numbers.

Because it is very reliable and efficient, it is used by almost all clients. So, using WebSocket is a trade-off between saving crucial bytes and enabling faster conversations at the cost of blocking a port for longer.

I know well that there can only be one process listening to a particular port, what I am actually having some problem undertand is the whole websocket thing, from what I understand, a websocket request begins with a HTTP handshake, after which there will be mechanism to 'upgrade' that session to the specific port. How Port Scanning with WebSockets Works WebSockets are intended to allow a site to create bi-directional communication like traditional network sockets. This allows sites to periodically send information to a client browser without user interaction or front end polling, which is a win for usability. In this way, a two-way ongoing conversation can take place between the client and the server. The communications are usually done over TCP port number 443 ( Many webSocket apps running from the browser wish to leverage existing security/login/auth infrastructure already being used on port 80 for the By default the WebSocket protocol uses port 80 for regular WebSocket connections and port 443 for WebSocket connections tunneled over TLS [ RFC2818].
