Traefik failing on POST request

[Tester98]

What version of Traefik are you using (traefik version)?

v1.1.2

What is your environment & configuration (arguments, toml...)?

linux, simple file backend

[retry]

[backends]
[backends.testing]
[backends.testing.servers.server1]
url = "http://primary:80"
weight = 1
[backends.testing.servers.server2]
url = "http://backup:80"
weight = 1

What did you do?

if the request is a POST request and if the primary backend has failed, then traefik will retry the request to backup ( or vice-versa first backup then primary).

What did you expect to see?

Request being forwarded to another server and a response

What did you see instead?

traefik fails to retry request and post data is destroyed. traefik debug logs below
