842701 - Don't add a charset to author-specified Content-Type in XMLHttpRequest

Status: RESOLVED FIXED

(Core :: DOM: Core & HTML, defect)

Description

[David Bruant]

Try on any page (with scratchpad):

var xhr = new XMLHttpRequest();
xhr.open('POST', '.')
xhr.setRequestHeader('Content-Type', "app/lication");
xhr.send('yo');

The WebConsole informs us that Content-Type header actually sent is "app/lication; charset=UTF-8"
It seems to be a Firefox violation of the XHR spec. Chrome seems to follow the spec, so that behavior looks web-compatible.

This has long since been fixed (the STR now work expected, with the header being sent as "app/lication").
