help needed in testing 1xx support

Hi HC devs!

I'm currently doing a little investigation on the support of 1xx
messages in Java HTTP clients, ranging from broken (HTTPURLConnection),
over "not broken" (Apache HttpClient4) to hopefully "fully supported"
(Apache HttpClient5).

I found
<https://hc.apache.org/httpcomponents-client-5.1.x/current/httpclient5/apidocs/org/apache/hc/client5/http/async/AsyncExecCallback.html#handleInformationResponse(org.apache.hc.core5.http.HttpResponse)>,
but I'm currently struggling how to use that from a minimal async client.

My current code is over here:


https://github.com/greenbytes/java-http-1xx-tests/blob/224c0f374622ce1c892498f7f148ed81eee1aa92/src/test/java/org/greenbytes/http/test1xx/TestHttp1xx.java#L128

and I'm trying to understand how to invoke "execute(...)" to actually
get access to the 1xx responses.

Pointers appreciated.

Best regards, Julian

Hi Julian

Here's an example of how one can use async HttpClient in a full duplex
mode including handling of intermediate informational responses:

https://github.com/apache/httpcomponents-client/blob/5.1.x/httpclient5/src/test/java/org/apache/hc/client5/http/examples/AsyncClientFullDuplexExchange.java

Hope this helps

Oleg
