Description Allan Jardine 2012-09-11 02:25:42 PDT 
If I attempt to create an EventSource connection to anything other than port 80 I get a security exception. For example:

new EventSource('http://192.168.1.11:65411/');
> 11550SECURITY_ERR: DOM Exception 18: An attempt was made to break through the security policy of the user agent

However, if I try to open a WebSocket on that same port, it works absolutely fine. Additionally, Firefox allows non-port 80 EventSources.

Perhaps there is a reason why only port 80 is allowed for EventSource, but it seems odd that WebSocket is allowed, while EventSource is not.

It's a known limitation, WebKit only supports same origin requests with EventSource.
