如@yjl所猜测，在IIS中，默认情况下，js对应的MIME type 确实是application/x-javascript。
参考：http://msdn.microsoft.com/en-us/library/bb742440.aspx，在页面中搜索javascript

解决办法有两个。

1. 将请求的Accpet字段中加一个application/x-javascript（我测试通过）。
2. 在IIS中给js添加text/javascript这个MIME type。(Configure MIME Types IIS 6.0)

这是不支持当前请求中的Accept Headers，题主检查一下是否限制了或者不支持以下MIME type、encoding算法、locale。

<code>Accept:text/javascript, application/javascript
Accept-Encoding:gzip, deflate, sdch
Accept-Language:zh-CN,zh;q=0.8
</code>

我觉得可能是限制了MIME type，限制Accept Headers的方式很多，具体操作还要看具体情况。

如Kavlez指出的，406的话，问题一般出在Accept, Accept-Charset, Accept-
Encoding, Accept-Language headers 这几个Header。

对于你的情况，应该是Accept:text/javascript, application/javascript的问题。可能server端用的是“application/x-javascript”，所以有406。你可以试着用Firefox/Chrome的REST Client插件，把你的Request的内容贴进去，然后把Accept:text/javascript, application/javascript替换成Accept:*/* (接受任何content types，BTW，这个type不指MIME type)，然后试试发送，应该会返回200OK。

可能是文件权限的问题，用的是nginx？
