Is it possible to Make HTTP/2 requests with Apache HTTPClient 4.2.5?

I'm trying to make an HTTP/2 request with apache client. Is it possible with the below versions?

migrating the versions in my web application cost me heavy code changes. Is there any workaround to support HTTP/2 with TLSv1.3 in httpclient-4.2.5.jar?

Apache libs i'm using:
httpclient-4.2.5.jar
httpcore-4.2.4.jar
httpmime-4.2.5.jar

Thanks in advance.

Solution

  • It looks like HTTP 2 is supported only from version 5. Apache Http Client Status

    The main focus of the 5.0 series is providing full-featured support for HTTP/1.1 and HTTP/2 and ensuring full compliance with RFC 7230, RFC 7231, RFC 7540 and RFC 7541.

    According to the Apache Http Client News it is still not a stable release of version 5.

    However, from Java 11, there is a new Http Client introduced with HTTP 2 support.

    It supports HTTP/1.1 and HTTP/2, both synchronous and asynchronous programming models
