Could you point out one such example? I've actually tested a fair
amount
They are in the current threads.
- "add" semantics for setRequestHeader
- semantics for setRequestHeader(...,null)
- silent data loss for send() when DOM can't be serialized
- ...
I think only for the last one I have suggested that I rather not change it
based on that this seems like a safer choice. I have not seen any tests
that show that implementations actually throw in that case.
of stuff, including headers, methods, etc. I agree that some of the
details of headers need to be worked out. For null/""/undefined I've
been waiting for the Web IDL specification. For which headers can be
set by the user agent I don't really have an answer and that part has
not been defined as such. That setRequestHeader() always appends was a
conscious choice to be in line with Internet Explorer. Initially the
design was so that it special cased a bunch of headers that did not
allow duplication which would have been more in line with Firefox, but
given that it is not a fixed list and the Internet Explorer route
seemed more appropriate.
Well, not to me. And apparently not to FF, as FF3 seems to ship with be
non-compliant behavior.
To my best knowledge Mozilla hasn't started implementing the specification
yet. I've seen several comments in their public bug database to the effect
that they rather wait until it reaches CR.
setRequestHeader() currently simply is broken. We should deprecate it,
and add new methods with well-defined semantics:
- removeHeader(...) (or specify set with null to mean remove)
- addHeader...
- getHeader...
"Deprecating" a method does not help implementations converge. Besides,
for typical usage there's no issue in using this header at all.
