Greetings Adrian, Sorry for the delay in responding to this email.
Strictly speaking, we could remove the Blob Protocol Version (BLV) [1]. It isn't returned in getAllResponseHeaders. BLV 's purpose was in case the protocol changes, and to differentiate between versions. But the protocol is internally consumed within the UA. I can remove it. --Original Message-- The current spec defines the Blob Protocol Version [1]. Our current implementation doesn't require a protocol version and the way protocol handlers are defined in Internet Explorer does require this. I don't know if this is ever exposed in the web platform. The spec says that this should be returned from XHR in getAllResponseHeaders [2] but I don't think XHR actually returns this string there. Please can someone help point me to where this is required? If it isn't exposed anywhere I think we can remove this section. Thanks, Adrian [1] http://dev.w3.org/2006/webapi/FileAPI/#ProtocolName [2] http://dev.w3.org/2006/webapi/FileAPI/#ProtocolExamples
