Also, I need to avoid roundtrips (407 & 401 errors). To do so in apache there is a concept of PreemptiveAuthentication. Is there any similar concept to this in netty? If yes, could you please help me in configuring the same.

@SushmaPradeep I'm looking at netty/netty#13892, there is no need to open duplicate issues!

@SushmaPradeep I am seeing that a request like this is sent.
17:23:58.216 [reactor-http-nio-1] DEBUG reactor.netty.proxy - [fd907a4e, L:/127.0.0.1:56744 - R:localhost/127.0.0.1:3128] WRITE, DefaultFullHttpRequest(decodeResult: success, version: HTTP/1.1, content: EmptyByteBufBE)
CONNECT example.com:443 HTTP/1.1
host: example.com:443
proxy-authorization: Basic <filter>
Can you please elaborate more on the issue? Can you provide either logs or tcp dump?

Thanks for quick responses @violetagg .
Yes, Iām also seeing this proxy_authorization in client side request context but not in outboundheaders or request object. Also, it is sending only scheme(basic) and not the encoded credentials. And this authorization value is not available in server side.
As I said I need to achieve preemptive authentication concept to avoid 407 roundtrips which is available with apache httpclient.
Could you please redirect me to the correct route to configure and achieve the same.

I have squid proxy configured with u/p.
I have this application:
public class Application {
public static void main(String[] args) {
HttpClient client =
HttpClient.create()
.wiretap(true)
.proxy(spec -> spec.type(ProxyProvider.Proxy.HTTP)
.host("localhost")
.port(3128)
.username("test")
.password(u -> "test"));
String response =
client.get()
.uri("https://example.com/")
.responseContent()
.aggregate()
.asString()
.block();
System.out.println("Response " + response);
}
}
When I'm executing this application I'm seeing a successful communication:

@SushmaPradeep I'm closing this one. We can reopen it if it is needed.

@violetagg Could you please re-open the issue. I'm using Hoverfly as proxy server. And I can't see proxy-authorization header.
Please find the below logs:
request={body=, destination=localhost:8094, headers={Accept=[text/plain, application/json, application/*+json, /], Accept-Encoding=[gzip, x-gzip, deflate], B3=[65dc9b4f308cd1148f70dd79c23841f2-c339dd05d8e4e80e-0], Content-Length=[0], User-Agent=[Apache-HttpClient/5.2.3 (Java/17.0.10)]}, method=GET, path=/api/v1/message, query={}, scheme=http}

@SushmaPradeep The user agent in this request is not Reactor Netty?
User-Agent=[Apache-HttpClient/5.2.3 (Java/17.0.10)]

Reactor Netty HttpClient uses always CONNECT method for proxy.
I installed Hoverfly and executed a request successful.
The application from above, just the port for the proxy is 8500.
