[undertow-dev] ProxyHandler is deprecated - what is it's replacement?

Hi all, I am using Undertow in my application and have noticed that ProxyHandler is deprecated: https://undertow.io/javadoc/2.0.x/io/undertow/server/handlers/proxy/Proxy... There doesn't seem to be anything in the docs about it's replacement, nor can I seem to find anything online about it. Does anyone know what the replacement is, if there is one? Thanks, Kevin
