Hi Eric, Sorry to be bugging you on this one, I grepped through the source and I see some solid references to trailer processing. From the change list, I found that you added support for MergeTrailers in 2.4.11 - any idea on how I could make it work? I just need apache to let the trailers pass through to the upstream haproxy, I am not processing them in mod headers or other apache modules.
