wrong content-length when proxy binary file

[cades]

as title, when I trying proxy binary file (which is served by koa-send), I found the content-length is wrong and file is corrupted.

Could anyone give me some suggestion to troubleshooting?

try to set encoding to "null" explicitly in proxy(path, encoding) and the underlying request module should handle the response as Buffer instead of a toString() (see documentation of "encoding" https://github.com/request/request).
