In the XMLHttpRequest spec, for setRequestHeader(), the spec states:
"If the header argument is in the list of request headers either use
multiple headers, combine the values or use a combination of those
(section 4.2, RFC 2616). [RFC2616]"
And RFC 2616 states:
"Multiple message-header fields with the same field-name MAY be
present in a message if and only if the entire field-value for that
header field is defined as a comma-separated list"
So, what should the UA do for headers that are not defined to be
comma-separated? For example, in the case of setting Content-Type twice
to two different values, does the latter override the former?
[...]
client.setRequestHeader("Content-Type", "text/plain");
client.setRequestHeader("Content-Type", "text/html");
client.send(data);
