Claus Ibsen commented on CAMEL-20099:
-------------------------------------
And yes I can see the bug in 4.1.0 when using --camel-version=4.1.0
{code}

So this is fixed in 4.2.0 onwards.
> Camel-http is creating invalid Content-Encoding header based on charset from

> Key: CAMEL-20099
> URL: https://issues.apache.org/jira/browse/CAMEL-20099
> Project: Camel
> Issue Type: Bug
> Components: camel-http
> Affects Versions: 4.1.0
> Reporter: Damir Palinic
> Assignee: Claus Ibsen
> Priority: Major
> Fix For: 4.0.3, 4.3.0
>
> Attachments: Screenshot 2023-11-14 at 09.12.12.png, Selection_894.png
>
>
> In case *Content-Type* header has *";charset=UTF-8"* suffix, camel-http
> component creates *Content-Encoding: UTF-8* header which is invalid by RFC
> specification.
> If you try to send request with *Content-Encoding: UTF-8* to SAP systems for
> example, they will reject it due to invalid header.
> YAML DSL to reproduce the issue:
>
> {code:java}
> - route:
> nodePrefixId: route-7e2
> id: route-dafc
> from:
> uri: scheduler
> id: from-64dc
> parameters:
> name: scheduler

> - setHeader:

> 01het4h4zq3gvtecszbv5rpx3y00-4f92b8ba4ea1459ece69.requestinspector.com
> httpMethod: POST
> {code}
> Additional notes:
> * If you remove ";charset=UTF-8" part from the Content-Type header, and call
> one more http request after the first one, it gets appended automatically for
> some reason, even if you remove Content-Type header and set it again manually
> (possible another bug) between two calls
> * Same behavior is for the https traffic
