Hi folks!
I was recently doing some experiments with Server-Sent Events
technology and come to an issue when EventSource url resource is from
a different origin (in my case different subdomain). When this happens
Chrome 13 gives this:
Uncaught Error: SECURITY_ERR: DOM Exception 18
and Firefox 6 this:
Firefox can't establish a connection to the server at ...url...
In my case requested EventSource url resource is using CORS specific
Access-Control-Allow-Origin header, but this doesn't help. So here
comes my question: does Server-Sent Events EventSource meant to
support CORS enabled url resource or this is a problem of browser
vendors (or maybe some other problem which I'm not aware of). Thanks
for your time and help.
Tomas
