Traefik setting Accept-Encoding: gzip on requests (Traefik may also be broken with chunked responses)

[severnt]

Setup:

• traefik beta794 prebuilt amd64
• nginx HTTP backend configured with file

For some reason, it looks like traefik is adding Accept-Encoding: gzip to the requests, which causes nginx to send back a chunked gzip response, which results in a 0 length 0 content-length response to the client. If I disable gzip on nginx, everything seems to work fine.

I've verified with packet caps that my client isn't setting the Accept-Encoding header, and that nginx is responding properly to the request.

Maybe due to containous/oxy@1832129. I need to investigate on this.

I suspect that this is due to a regression that occurred in v1.0.0-beta.754 #398.
Could you test using v1.0.0-beta.744 instead? I cannot reproduce this issue on my laptop.
