The WebSocket protocol is implemented in different web browsers, web servers, and run-time environments and libraries acting as clients or servers. The following is a table of different features of notable WebSocket implementations.
The client sends an HTTP request (method GET, version ≥ 1.1) and the server returns an HTTP response with status code 101 (Switching Protocols) on success.This means a WebSocket server can use the same port as HTTP (80) and HTTPS (443) because the handshake is compatible with HTTP.
Since the changes to the websocket protocol versions 8-13, the HLL Websocket Server is one of the few (maybe the only for a while) with an actual live demonstration using the updated protocol, which has now been submitted to become the actual standard. There are very few experts on websockets at this point.
The server, if it supports the protocol, replies with the same Upgrade: WebSocket and Connection: Upgrade headers and completes the handshake. [3] Once the handshake is completed successfully, data transfer begins.
Lightstreamer implements a bi-directional transport based on standard Web protocols. This means it uses several underlying techniques (WebSocket, Comet, HTTP streaming, etc.) to provide the upper layers with a channel over which data can be exchanged in real-time with any client connected through the Web, even if protected by firewalls and proxies.
Settings may be in a different location in each email client, though the AOL server and port settings will always be the same. For additional questions specific to the email client, check the manufacturer’s website. Manufacturers cannot answer questions about your AOL Mail settings, or your AOL username or password.
Socket.IO primarily uses the WebSocket protocol with polling as a fallback option, while providing the same interface. [5] Although it can be used simply as a wrapper for WebSockets, it provides many additional features such as heartbeats and timeouts. [5] It can be installed with the npm (Node Package Manager). [6]
Line 2 receives an incoming event, for example, HTTP request or WebSocket message. The await keyword is used because the operation is asynchronous. Line 4 asynchronously sends a response back to the client. In this case, it is a WebSocket communication.
