Hi Mark Classic client APIs in HttpClient 5.0 will give you very similar, mostly compatible APIs with HttpClient 4.x but no HTTP/2. If you want to utilize HTTP/2 you should be using async APIs provided by HttpClient 5.0. HttpAsyncClient is perfectly capable of streaming both request and response data (in full-duplex if desired) but you would lose convenience of InputStream/OutputStream APIs and would need to structure your application logic in terms of callback methods reacting to various events during HTTP message exchanges: https://github.com/apache/httpcomponents-client/blob/master/httpclient5 /src/examples/org/apache/hc/client5/http/examples/AsyncClientHttpExchan geStreaming.java https://github.com/apache/httpcomponents-client/blob/master/httpclient5 /src/examples/org/apache/hc/client5/http/examples/AsyncClientFullDuplex Exchange.java Oleg --------------------------------------------------------------------- To unsubscribe, e-mail: httpclient-users-unsubscr...@hc.apache.org For additional commands, e-mail: httpclient-users-h...@hc.apache.org
