Hello guys is there any way to add headers to all request in Ktor? I've tried to add them via buildHeaders { append("foo","bar" } but looks like is not working if I add them in the request it works...
it's weird.

httpClient.get<FooResponse>("<https://foo.bar>"){header("foo","bar")} <-- it works

Any idea why?

Yes, with a feature.

I think defaultRequest could probably do it.

Yep, defaultrequest will do

https://ktor.io/docs/default-request.html#installation

It is the canonical example in the documentation

Just be aware of the fact that HttpRequestBuilder.header() function appends the value if the header is already set.

Is there any way to verify that it's adding the headers? I have this

engine {
                val loggingInterceptor = HttpLoggingInterceptor()
                loggingInterceptor.level = HttpLoggingInterceptor.Level.BASIC
                addInterceptor(loggingInterceptor)
            }

I've tried to use Level.HEADERS but don't see them
