Nginx proxy_pass with urls with no content-length headers

I’ve found a small issue with proxy_pass when passing urls that don’t
have a content-length field.

Nginx is adding a content-field length of 221183499 rather then just not
including the header.

The way to test this is to proxy pass something like an icecast stream
