HTTP/2 client and closed connections
Hello, I am building an HTTP/2 only client for running multiple requests in parallel. I understand that there is no connection pool internally, rather there is one connection per host. For simplicity, let's say all my requests go to the same host. I have a situation where under stress there are some errors. It starts with socket timeout (several threads in parallel), and after a while there is a ConnectionClosedException. I am not sure what is the flow of events that leads to this, and what is the relationship between those errors. I also don't know if it is my client or the server that closed the connection. My initial question is, since there is only one connection maintained internally, how does one recover from ConnectionClosedException? The connection life-cycle is opaque to me - there is no pool, and no eviction strategy, so no concept of creating a new connection. So what am I missing? Is the httpClient object still usable after a ConnectionClosedException? Somewhat related, I am looking at the sample here: https://hc.apache.org/httpcomponents-client-5.3.x/migration-guide/migration-to-async-http2.html What is the difference between the two socket timeout configurations, on IOReactorConfig and ConnectionConfig? What is the time to live? Thanks, Jonathan

One can pretty much do with HTTP/2 all what Websockets can do.

Websocket client using ReactiveResponseConsumer and ReactiveEntityProducer
Hi, I am writing a websocket client with APIs ReactiveResponseConsumer and ReactiveEntityProducer. Once the websocket server completes the handshake by upgrading connection and returning 101. We do get Http status code and headers after the handshake completes. But not Publisher. So we get httpStatus and headers from https://github.com/apache/httpcomponents-core/blob/master/httpcore5/src/main/java/org/apache/hc/core5/http/impl/nio/ClientHttp1StreamHandler.java#L210 But it returns if the status code is less 200. https://github.com/apache/httpcomponents-core/blob/master/httpcore5/src/main/java/org/apache/hc/core5/http/impl/nio/ClientHttp1StreamHandler.java#L229 We want it to consume entity details so we get Publisher https://github.com/apache/httpcomponents-core/blob/master/httpcore5/src/main/java/org/apache/hc/core5/http/impl/nio/ClientHttp1StreamHandler.java#L249 Could you help figuring this out? Thanks, Sneha
