- In the Advanced Settings section, set Show Advanced Settings to Yes and click Save.
- Go to the BASIC > Services page.

How scalable are WebSockets?
Compared to REST, WebSockets allow for higher efficiency and are easier to scale because they do not require the HTTP request/response overhead for each message sent and received. Furthermore, the WebSocket protocol is push-based, enabling you to push data to connected clients as soon as events occur.
How many WebSockets can a server open?
By default, a single server can handle 65,536 socket connections just because it’s the max number of TCP ports available.
When should I use WebSockets?
When a client needs to react quickly to a change (especially one it cannot predict), a WebSocket may be best. Consider a chat application that allows multiple users to chat in real-time. If WebSockets are used, each user can both send and receive messages in real-time.
How do you use WebSockets?
In order to communicate using the WebSocket protocol, you need to create a WebSocket object; this will automatically attempt to open the connection to the server. The URL to which to connect; this should be the URL to which the WebSocket server will respond.
Can WebSocket go through load balancer?
The load balancer knows how to upgrade an HTTP connection to a WebSocket connection and once that happens, messages will travel back and forth through a WebSocket tunnel. However, you must design your system for scale if you plan to load balance multiple WebSocket servers.
