Sure.
I have a setup where we're using HAProxy to front hundreds of different
services, each service running on a different port.
I can figure out from the request (for example, the SNI information), which
service we want to use. However, for maintenance of the haproxy config
file,
it's very desirable to not have several hundred back-ends.
A frontend, with a server configuration with a dynamically chosen port seems
ideal. It would be the logical equivalent of
server svc1 host:1001 if svc_1
server svc2 host:1002 if svc_2
etc.
Thanks,
