Then we end up at https://dvcs.w3.org/hg/xhr/raw-file/tip/Overview.html#cross-origin-request-steps and then at http://www.w3.org/TR/cors/#cross-origin-request where presumably "If for some reason the user agent does not want to make the request terminate this algorithm and set the cross-origin request status to network error." In this case the "some reason" is "I have no idea what to do with this scheme". -Boris

Let's go with network error for now then. That's what http://fetch.spec.whatwg.org/ calls for and has always been the intent of the XMLHttpRequest specification although not explicitly called out. It's what CORS does for complex requests that get a redirect back, too. -- http://annevankesteren.nl/

Those two caveats apply to everything, I suppose ;-) Anyway - it's your call but if you're undecided maybe we should not work on that Gecko bug just yet? If you make your mind up we can deal with 918772 when someone gets around to it, if not please comment in the bug tracker. (AFAIK Gecko is the only engine with this behaviour, although I'm not able to test IE because I don't have a Win7 or 8 machine and lesser IE versions don't work well with the test framework.) -Hallvord

Once I get to redefining XMLHttpRequest in terms of http://fetch.spec.whatwg.org/ it would be I think. Not sure it makes sense to return the erroneous redirect response instead, although I suppose that might make polyfilling easier if we do it right and implementations get all the details correct. -- http://annevankesteren.nl/
