spring-cloud-netflix: 411 Content Length required issue

For some reason, my home ISP throws 411 Content length required error when I try to post something to the cloud rest endpoint thru locally running zuul proxy. So I tried setting content-length header manually from a custom filter like: ctx.addZuulRequestHeader("content-length", ctx.getRequest().getHeader("Content-Length"));

But it throws

com.netflix.zuul.exception.ZuulException: Forwarding error...
Caused by: org.apache.http.ProtocolException: Content-Length header already present
    at org.apache.http.protocol.RequestContent.process(RequestContent.java:95)
    at org.apache.http.protocol.ImmutableHttpProcessor.process(ImmutableHttpProcessor.java:131)

    at org.apache.http.impl.client.DefaultRequestDirector.execute(DefaultRequestDirector.java:485)
    at org.apache.http.impl.client.AbstractHttpClient.doExecute(AbstractHttpClient.java:863)

I’m using Zuul 1.0.28. Am I doing anything wrong? I’m not even sure if the original problem would disappear if I manage to set this header manually. Any suggestion, anything would be very much appreciated.

p.s: ISP allows my post request when its done thru Feign.

@nissel I’ve since made changes that always propagate content-length: https://github.com/spring-cloud/spring-cloud-netflix/blob/master/spring-cloud-netflix-core/src/main/java/org/springframework/cloud/netflix/ribbon/support/ContextAwareRequest.java#L45

We’re fairly close to a 1.1.3. There won’t be any milestones or RC’s.
