如何从使用 gzip 编码的服务器在 Rhino 中加载 javascript 库？

在 rhino 中，我习惯于能够从 URL 加载 javascript 库，例如

load('http://latex.mathoverflow.net/mathjax/MathJax.js')

（这实际上不起作用，除非您首先通过 env.js 或类似的方式提供类似浏览器的环境。但是 rhino 设法获取文件，然后开始编译它。）

但是，如果服务器提供了压缩的 javascript 库，rhino 似乎会立即失败并出现语法错误，例如

load('http://cdn.mathjax.org/mathjax/latest/MathJax.js')

您可以使用curl 看到差异，例如

curl --head http://latex.mathoverflow.net/mathjax/MathJax.js

Gives

有什么建议吗？有没有什么技巧可以让rhino加载gzip压缩的脚本？

原文

In rhino, I'm used to being able to load javascript libraries from a URL, e.g.

load('http://latex.mathoverflow.net/mathjax/MathJax.js')

(This doesn't actually work, unless you provide a browser-like environment first, via env.js or similar. But rhino manages to get the file, and start compiling it.)

However, if the server provides the javascript library gzipped, rhino seems to fail immediately with syntax errors, e.g.

load('http://cdn.mathjax.org/mathjax/latest/MathJax.js')

You can see the difference using curl, e.g.

curl --head http://latex.mathoverflow.net/mathjax/MathJax.js

gives

Any suggestions? Is there a trick to allow rhino to load gzipped scripts?
