HaProxy in front of Openlitespeed server with send_proxy


We are setting up our servere environment and we have some issues with it.

We are using a haProxy in front of our Openlitespeed serveres.
We configured the haProxy to use send_proxy (proxy protocol, RemoteIPProxyProtocol)

But we cant get it to work when we use send_proxy. Removing send_proxy works but the we get the ip of the proxy server instead of the client ip.

When we google this we found this comment.
That's true that RemoteIPProxyProtocol is not supported by litespeed. so the extra header sent by the layer4 proxy breaks the SSL handshake.

Does this mean that the openlitespeed does not support proxy protocol?
