---------------------------------------

             Summary: camel-vertx-http: Headers may get erroneously duplicated 
                 Key: CAMEL-19018
                 URL: https://issues.apache.org/jira/browse/CAMEL-19018
             Project: Camel
          Issue Type: Bug
          Components: camel-vertx-http
    Affects Versions: 4.0-M1, 3.20.2, 3.18.5
            Reporter: James Netherton
            Assignee: James Netherton
             Fix For: 3.18.6, 3.20.3, 3.21.0, 4.0-M2


Given routes configured like this:

{code}
rest()
        .post("/greeting")
        .to("direct:greet")

        .post("/hello")
        .to("direct:hello");

from("direct:greet")
        .removeHeaders("CamelHttp*")
        .to("vertx-http:http://localhost:8080/hello?httpMethod=POST");

from("direct:hello")
        .setBody().simple("Hello ${body}");
{code}

When using cURL to POST to /greeting, the response reveals some of the headers get duplicated:

{code}
< HTTP/1.1 200 OK
< Accept: */*
< Accept: */*
< User-Agent: curl/7.81.0
< User-Agent: Vert.x-WebClient/4.3.7
< User-Agent: curl/7.81.0
< Content-Length: 17
< Content-Type: [application/json, application/json]
{code}
