Re: [undertow-dev] Proxy Protocol/Layer-4 load balancing/AWS ELB
I think ELB constitutes pretty wide usage. ;-)
People do tend to use the layer-7 load balancing, but given undertow's
extensive support for http/2 & spdy, the advantages of using layer-4 load
balancing are significant. I agree it is a very straightforward
implementation. You mostly just parse one line before handing off the logic
to some other handler. I'm not familiar with undertow's code base, but I'd
be happy to work with someone on it.

ELB supports layer-4 load balancing, which would just multiplex inbound
TCP connections (with an added bonus of offloading TLS), but I'm concerned
about losing client IP addresses. ELB actually has a way to address this
with HAProxy's PROXY protocol:

However, I haven't found a place for setting up the PROXY protocol support
in undertow. Has anyone done this? Is there a way I should be going about
it?
We should probably add support for haproxy's protocol if it has wide usage
like this. It looks fairly straightforward.
