Nginx as reverse proxy, returns garbage symbols

Hi everyone,
I am trying to use nginx as a reverse proxy and I am getting garbage
symbols
in my json responses:

6a
{“codedField”:[{“code”:“01”,“name”:“Dpto01”},{“code”:“02”,“name”:“Dpto02”},{“code”:“03”,“name”:“Dpto03”}]}
0

I have tried with and without gzip and happens the same.

My backend responses are well formed json and then I think that it
should be
a nginx issue.

Can anybody help me please ?

Regards,

Camilo Aguilar

Looks like your backend returns Transfer-Encoding: chunked to
HTTP/1.0 requests (behaviour explicitly forbidden by RFC2616).

Fixing backend should help.

This patch was considered to be wrong as it potentially introduce
much more problems than it solves. E.g. strange things will happen
if any content filtering within nginx will be used (gzip, ssi,
addition or sub filters and so on).

It may work in your particular case, but I don’t recommend it.
Fixing backend instead is much more correct and safe aproach.

Thanks Maxim for your quick answer,
Do yo know something about nginx talking to backends in http 1.1 ?
