I brought this up a while ago as well: http://lists.whatwg.org/htdig.cgi/whatwg-whatwg.org/2010-October/028868.html
Echoing Ilya: this is actually a very important feature because generally you don't want long-lived connections (HTTP streaming) and short-lived connections (web page requests) going through the same hosts. -Nicholas ______________________________________________ Commander Lock: "Dammit Morpheus, not everyone believes what you believe!"

See http://en.wikipedia.org/wiki/XMLHttpRequest#Cross-domain_requests. I filed a request with WebKit bugzilla and they suggested to send it to you: https://bugs.webkit.org/show_bug.cgi?id=61862 The rationale and use cases are exactly the same as for XHR: it can be useful to access different domains. Is support for EventSource cross domains planned at all? It is supposedly one of the most requested features, but I do not know how it is tracked. Thanks
