Why is Ktor client sending Accept: application/xml;application/json header when I call:

<http://httpClient.post|httpClient.post>(serviceUrl) {
                contentType(ContentType.Application.Json)
                accept(ContentType.Application.Xml)
                body = MyClass(...)
            }

Does such header even conform to HTTP standard?

[Robert Jaros]

This is how httpClient is defined:

val httpClient = HttpClient(Apache) {
        install(JsonFeature) {
            serializer = KotlinxSerializer()
        }
        engine {
            socketTimeout = 60_000
        }
    }

Content types in the Accept header should be separated by a comma, am I right?

[Dennis]

https://tools.ietf.org/html/rfc2616#page-100 says its a semicolon

[Dennis]

oh no, parameters are separated by semicolon

Accept: text/plain; q=0.5, text/html, text/x-dvi; q=0.8, text/x-c
