JSONP Long Polling always loading.

Question

I'm doing long-polling with JSONP and firefox continually pops up the "Loading" spinner making the page seem like it hasn't finished loading. Is there a way to suppress this?

I've been told that the Orbited team has hacks for suppressing this, but looking through the Orbited.js code I cannot figure out what they are. Any help would be greatly appreciated.

Answer 1

I don't have an answer, but I do have a suggested alternative. Someone else just asked a similar question and here's my answer.

Basically, if you have control of the server, the simplest solution is to use Cross-Origin Resource Sharing headers to OK cross-domain XMLHttpRequest and fall back to JSONP on old browsers.

I've provided a reasonably complete compatibility table (every userscript-capable browser) for CORS as part of the answer I linked to, as well as a more general one on Wikipedia.
