Hi,
In XHR [1], setRequestHeader is defined by this:
[[
void setRequestHeader(ByteString name, ByteString value);
]]
It has a note:
[[ Throws a SyntaxError exception if name is not a header name or if value is
not a header value. ]]
In WebIDL [2], ByteString is defined by the algorithm
[[
• Let x be ToString(V).
• If the value of any element of x is greater than 255, then throw a
TypeError.
• Return an IDL ByteString value whose length is the length of x, and
where the value of each element is the value of the corresponding element of x.
]]
So what should be thrown when one does
var client = new XMLHttpRequest();
client.open('GET', '/glop');
client.setRequestHeader('X-Test', '小');
TypeError per WebIDL or SyntaxError per XHR?
I think it should be TypeError, and SyntaxError for code <256 that are not
allowed, but implementations currently use SyntaxError only.
