From this I suspect that the scheme could be anything: http, https, mailto, irc, etc. In the context a script I was wondering if iframe.contentWindow.postMessage('message','http://dev.opera.com') could be rewritten iframe.contentWindow.postMessage('message','//dev.opera.com') allowing Web sites to work with or without https without having to rewrite the code. If this is authorized maybe, the paragraph could be modified with It represents, in server-sent events and cross-document messaging, the origin of the document that sent the message (typically the scheme null string included, hostname, and port of the document, but not its path or fragment identifier). Some examples of valid origin values http://foo.example.com https://foo.example.com //foo.example.com 64149 1 zcorpan 2012-02-15 19:39:58 +0000 The scheme can't be omitted. However, if you want "allow the same origin as myself", there's a special value for that, "/". 64152 2 karl+w3c 2012-02-15 20:04:17 +0000 (In reply to comment #1) > The scheme can't be omitted. However, if you want "allow the same origin as > myself", there's a special value for that, "/". Ah thanks. This could be put in the specification too. Though that doesn't solve the use case I was mentioning. Hmmm too bad, I guess.
