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. 57845 3 ap 2007-10-05 05:25:02 -0700 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. 651236 4 tzik 2012-06-18 01:13:40 -0700 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 1210025 5 youennf 2016-07-12 08:10:05 -0700 *** This bug has been marked as a duplicate of bug 109199 *** 14826 2007-06-01 11:53:52 -0700 2007-06-01 11:53:52 -0700 HTML that does a XHR on data://URL xmlHttpRequest_data_url.html text/html 726 just1gb PGh0bWw+DQo8aGVhZD4NCjwvaGVhZD4NCjxib2R5Pg0KPGRpdiBuYW1lPSJ4eHgiIGlkPSJ4eHgi PiA8L2Rpdj4NCjxzY3JpcHQ+DQoNCnZhciByZXEgPSBuZXcgWE1MSHR0cFJlcXVlc3QoKTsNCiAv L3ZhciB1cmwgPSAiaHR0cDovL3d3dy5nb29nbGUuY29tIjsNCnZhciB1cmwgPSAnZGF0YTp0ZXh0 L2h0bWw7Y2hhcnNldD11dGYtOCwlM0MhRE9DVFlQRSUyMEhUTUwlMjBQVUJMSUMlMjAlMjItJTJG JTJGVzNDJTJGJTJGRFREJTIwSFRNTCUyMDQuMCUyRiUyRkVOJTIyJTNFJTBEJTBBJTNDaHRtbCUy MGxhbmclM0QlMjJlbiUyMiUzRSUwRCUwQSUzQ2hlYWQlM0UlM0N0aXRsZSUzRUVtYmVkZGVkJTIw V2luZG93JTNDJTJGdGl0bGUlM0UlM0MlMkZoZWFkJTNFJTBEJTBBJTNDYm9keSUzRSUzQ2gxJTNF NDIlM0MlMkZoMSUzRSUzQyUyRmJvZHklM0UlMEQlMEElM0MlMkZodG1sJTNFJTBEJTBBJzsNCnJl cS5vcGVuKCdHRVQnLCB1cmwsIHRydWUpOw0KcmVxLm9ucmVhZHlzdGF0ZWNoYW5nZSA9IGZ1bmN0 aW9uKGFFdnQpIHsNCiAgaWYoIHJlcS5yZWFkeVN0YXRlID09IDQgJiYgcmVxLnN0YXR1cyA9PSAy MDApIHsNCiAgICB2YXIgZGl2X2lkID0gZG9jdW1lbnQuZ2V0RWxlbWVudEJ5SWQoJ3h4eCcpOw0K ICAgIGRpdl9pZC5pbm5lckhUTUwgPSByZXEucmVzcG9uc2VUZXh0Ow0KICB9DQogfQ0KcmVxLnNl bmQobnVsbCk7DQoNCjwvc2NyaXB0Pg0KPC9ib2R5Pg0KPC9odG1sPg0K
