Meteor uses JavaScript as its primary programming language, enabling developers to use a single language for both client-side and server-side code. [ citation needed ] This approach can streamline the development process for mobile applications by reducing the need for additional programming languages.
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.
WebSocket also uses this mechanism to set up a connection with a HTTP server in a compatible way. [2] The WebSocket Protocol has two parts: a handshake to establish the upgraded connection, then the actual data transfer.
Modern browsers will permit a script to connect to a WebSocket address without applying the same-origin policy. However, they recognize when a WebSocket URI is used, and insert an Origin: header into the request that indicates the origin of the script requesting the connection. To ensure cross-site security, the WebSocket server must compare ...
In this context, a socket is externally identified to other hosts by its socket address, which is the triad of transport protocol, IP address, and port number. The term socket is also used for the software endpoint of node-internal inter-process communication (IPC), which often uses the same API as a network socket.
AMQP is a binary application layer protocol, designed to efficiently support a wide variety of messaging applications and communication patterns. It provides flow controlled, [3] message-oriented communication with message-delivery guarantees such as at-most-once (where each message is delivered once or never), at-least-once (where each message is certain to be delivered, but may do so ...
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]
This means that the SSH server will only be aware of the IP address of the web application server, keeping the actual client's IP address hidden. Auditability: Because all communication between the client and the SSH server must pass through the web application server this communication can be logged. This prevents a malicious client from ...
