             Summary: camel-platform-http-vertx: Allow response headers with empty values to be returned
                 Key: CAMEL-19078
                 URL: https://issues.apache.org/jira/browse/CAMEL-19078
             Project: Camel
          Issue Type: Improvement
          Components: camel-platform-http-vertx
    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


If you have a platform-http-vertx endpoint defined like:
{code:java}
from("platform-http:/hello")
    .setBody().constant("Hello World");
{code}
Then make a cURL request like this where 'header-b' has an empty value:
{code:java}
curl -v -H "header-a: value-a" -H "header-b;"  localhost:8080/hello 
{code}
The response headers usually echo back any custom headers. But in this case 'header-b' is not present as it gets mistakenly filtered out.
{code:java}
Accept: */*
header-a: value-b
User-Agent: curl/7.81.0
{code}
Some apps require such headers to be returned in the HTTP response, so we should support this.
