This does not work in Firefox either, and handling of data:// URLs is not specified in draft XMLHttpRequest spec. Does this work in Internet Explorer? I'm particularly suspicious about the "req.status == 200" check - status is HTTP-specific, and does not apply to other protocols. Also, what are the use cases for this? I mean, instead of loading a data:// URL, one can just use a string literal.

It seems that Opera is the only browser that supports XHR on data:// URLs, and this feature is unlikely to get into the spec. See the thread <http://lists.w3.org/Archives/Public/public-webapi/2007Oct/0001.html>. Since no use cases were presented, I don't see any value in implementing this.

Could you reconsider this? Now, Firefox and Opera supports XHR for data: URL and some APIs have interface to get content as data: URL. https://bugzilla.mozilla.org/show_bug.cgi?id=702820
