Hi! Could anyone explain me why RibbonRoutingFilter drops Content-Length header from request object? Is there any option to disable this transformation?
I talk about Zuul filter.

I think it causes problems with certain kinds of request (chunked encoding maybe). It doesn't completely drop it, just replaces it with one computed by the client, IIRC.
i.e. you should see a content length in downstream services

my problem that request like "curl -X POST -d'{"dsdsd":12}' -H 'Content-Length: 2' -i localhost:8765/dev/api/providers/test" passing through Zuul filter converts to something like:
content-type : application/x-www-form-urlencoded
accept-encoding : gzip
user-agent : curl/7.43.0
accept : /
netflix.nfhttpclient.version : 1.0
x-netflix-httpclientname :providers
transfer-encoding : chunked
connection : Keep-Alive

That looks valid on the downstream side (and invalid upstream because the content-length is wrong)
I would rather have a correct header than a wrong one
What are you expecting?

I expect that request will not has transfer-encoding : chunked header. I have problem with request processing in python microservice since uwsgi does not support chunked request
I want to control this this behaviour by myself since i want to use different clients in my infrasturcture

Then you need to get control of the client
You can do that to some extent with Ribbon
It's not completely open though IIRC
I doubt if there is literally nothing in the python stack that supports chunked encoding though
This is standard HTTP
So if you control the back ends I would look to change those first
