Class Http2StreamHeaderCleaner

java.lang.Object
io.netty.channel.ChannelHandlerAdapter
io.netty.channel.ChannelInboundHandlerAdapter
com.netflix.zuul.netty.server.http2.Http2StreamHeaderCleaner
All Implemented Interfaces:
io.netty.channel.ChannelHandler, io.netty.channel.ChannelInboundHandler
@Sharable public class Http2StreamHeaderCleaner extends io.netty.channel.ChannelInboundHandlerAdapter
The Http2ServerDowngrader currently is always incorrectly setting the "x-http2-stream-id" header to "0", which is confusing. And as we don't actually need it and the other "x-http2-" headers, we strip them out here to avoid the confusion. Hopefully in a future netty release that header value will be correct and we can then stop doing this. Although potentially we _never_ want to pass these downstream to origins .... ?
