Confusion about long-polling in the HTMX tutorial

[FantasyTeddy]

Hi, I'm currently reading through the excellent HTMX for ASP.NET Core Developers tutorial and I'm a little bit confused about the term "long-polling" in the Long-Polling to get recent updates chapter.

My understanding of long-polling is, that it does not require constant client-side polling (as in the tutorial example), but allows the server to delay its response until something "interesting" happens.

For the provided stock value example, I would have expected the following:

• On the client-side, the hx-trigger should be (close to) immediate.
• ... and on the server-side, the GET request should probably be asynchronous and wait for some kind of "stock value changed" event until it sends a response.

Is my understanding of long-polling wrong, or is the example just "polling"?

I guess I've been using the term interchangeably, but there seems to be a distinction. You are correct. Thanks for teaching me something.

Thank you for confirming. I'm glad I did not misinterpret something :)
