micronaut.server.netty.legacy-multiplex-handlers

boolean

Prior to 4.4.0, the Micronaut HTTP server used a multi-pipeline approach for handling HTTP/2 connections where every request got its own netty pipeline with HTTP/2 to HTTP/1.1 converters on the pipeline. This allowed for using mostly unchanged HTTP/1.1 in the request handling and any NettyServerCustomizers. <p> As of 4.4.0, this approach was replaced with a more performant HTTP/2-specific implementation. This means worse compatibility with HTTP/1.1-based code paths and customizers, however. Setting this option to {@code true} returns to the old behavior.
