Re: Websockets on the IBMi

From: Kevin Turner
The huge benefit of websockets is that you can have a permanent
connection between the client and the server

You can do that with XMLHTTPRequest objects as well. The Apache server supports persistent connections.

and the server can "push" events to the browser,

I've read that from a number of sources on the Web. But I don't think it's true. WebSockets just hides the request-response cycle. TCP/IP is fundamentally a request-response protocol. A server won't push anything to a client without a client requesting it first.

rather than the browser having to poll the server periodically.

A push mechanism is far more efficient that a long polling mechanism.

As I already indicated, I think Web Sockets are still polling the server. But it's not apparent.
