"Failed to parse url" error when fetching a relative url

[blaise-io]

When I fetch a relative url, I get these errors on master:
LOG: xdomain (http://blaise.local:8000): failed to parse url: /some/relative/url/

I would expect relative url's (protocol-relative, host-relative) to work. Maybe patch parseUrl to prepend the master's protocol if the protocol is unspecified, and return the master's origin if no hostname is specified?

Environment: Windows 7, IE9, Strict mode.

Ah, that's just a noisy parse function. Relative URLs are destined for the current origin, so XDomain will not hook them. The log is XDomain failing to find an origin in the URL and therefore ignores it, though normal XHR should still work. This should only appear when debug is enabled. If it's not working, then I'm quite sure it's something else, most likely related to #38. Hard to debug atm since I don't have a Win7 machine active, will need to create a VM i guess...

I can also reproduce it in the latest Firefox, if that helps your testing :)
In my project I'm only using this library for IE9 and below.

I managed to patch it quick-and-dirty using the code below, but I'm sure there's a more elegant way of fixing this.

        if (url) {
            // Patch protocol-relative URL
            if (url.match(/^\/\//)) {
                url = location.protocol + url;
            }
            // Patch domain-relative URL
            else if (url.match(/^\//)) {
                url = location.protocol + '//' + location.host + url;
            }
        }

Oh damn, just tested, its all browsers - requests to relative URLs fail, investigating now...

fixed, thanks for the heads up, turns out i was missing 4 characters: if p

Thanks for fixing the relative url issue so quickly!

However, I still have an issue when using protocol-relative url's.
Could you also pick up this specific issue? (reproducable in IE and Firefox)

• Fetching https://master.example.org/path.html works fine.
• Fetching //master.example.org/path.html shows an error:
  xdomain (https://slave.example.org): failed to parse url: //master.example.org/path.html

I'm using data-master="*" on my slave.
