对于Windows手机上的XHR（8.1，Lumia 925），我有一种奇怪的行为。
我正在使用javascript库来执行一些XHR请求（Tin Can JS库），并且它对外部URL执行PUT设置一些标头。 如果我在IE11上运行与网页完全相同的代码，请求会发送以下标题：
Accept: */*, referer: http://169.254.80.80:8080/dest/

如果我在Windows Phone上运行它，由Cordova包装，这些是标题：

特别缺少的是Authorization标头。我通过console.log进行了检查，并且即使在Windows手机上也执行了相应的xhr.setRequestHeader，但似乎标题被丢弃或被忽略。
我无法找到导致此问题的原因或解决方法。
