HTTP2 with Conscrypt Security provider

Description

This very simple app demonstrates using Jetty's HTTP2 capabilties.

This sample should work with JDK 8 and up, and uses Google Conscrypt Security Provider (which uses Google's OpenSSL fork, BoringSSL). This means you don't need a bootclasspath agent to patch JDK8 libs, and you don't need to worry about JDK9+ libs. Additionally, It should have better performance than the Java native libs.

Usage

  1. Start the application: lein run
  2. Go to localhost:8080 to see an HTTP 1.1 message.
  3. Go to localhost:8443 to see an HTTP2 message.

You can also use an HTTP2-enabled command line client:

  1. Direct HTTP2 clear-text request: nghttp -v http://localhost:8080/
  2. Upgrade an HTTP/1.1 request to a clear-text HTTP2 request: nghttp -vu http://localhost:8080/

Enabling HTTP/2 Push

Jetty fully supports HTTP/2 Push. The easiest way to hook up Push for all requests is with a ServletFilter - PushCacheFilter or PushSessionCacheFilter.

You can also Push individual resources by hand, grabbing the PushBuilder directly from the Servlet Request.

You can find more information in the Jetty docs for configuring HTTP/2 Push.
