there was some legacy code expecting headers to be all caps and amazon rewrites them to all lower case when they pass through the traffic
that was a fun one to figure out
Do you mean the new DO LBs or something else? The DO LBs are not referred to as 'elastic' / ELBs.
I've just set up a DO LB and it's HTTP 1.1 all the way.
Edit: have confirmed with Digital Ocean: no HTTP/2 support (there's HTTP/2 passthrough, but you can't terminate there).
They do support ECC certs though.
