Description Anne 2012-01-10 20:41:07 UTC 
User agents start to allow fetching of data URLs in the context of XMLHttpRequest. That has implications for status/statusText/getResponseHeader()/getAllResponseHeaders(). Those implications need to be defined. Ideally in the data URL standard just like they are for blob URLs, but otherwise maybe in XMLHttpRequest for now.

Henri also suggested adding a note to those four members to point out this issue to implementors.

Henri, is this good enough?

I think you should handle the case where the data URI does not include the media type.

Choices:

a) use the defined default, or

b) do not define the Content-Type header field

b) is probably less surprising.
Comment 3 Anne 2012-02-16 14:43:58 UTC 
I think we should include it, otherwise for "document" it would be treated as XML.
