Answer 1

According to Wikipedia, HTTP Streaming comet is supposed to be possible in every browser. "Page Layout with Frames that Aren't", Ajax: The Definitive Guide. O'Reilly Media, pp. 320.

It's definitely possible: GMail does it. If you watch the Resources section of the developer tools in the latest Webkit, you can watch it in action. They have a request called "bind" that stays open more or less indefinitely. My understanding is that when new mail arrives, it comes across that connection.

Answer 3

Yes.

You need to include a large amount (at least 256 bytes) of junk at the front of the response in order to get Safari to behave.
