Request-Response over WebSockets
Learn techniques to simulate traditional request-response semantics using WebSocket message IDs and acknowledgments.
Beyond Fire-and-Forget
WebSockets are fantastic for real-time, continuous streams of data. Think chat messages, live updates, or game states!
But what if you need to perform a traditional request-response interaction, like fetching specific data from a server and expecting a single, matching reply?
The Asynchronous Nature
Unlike HTTP, where each request gets an immediate, direct response, WebSockets operate on an asynchronous, message-based model.
When you send a message over a WebSocket, you don't automatically know which incoming message is its specific reply. It's like sending a letter and waiting for a specific reply letter in a pile of mail!
