HTTP/2.0 Server-Side Traffic

Hi,   As I understand it now, the HTTP/2 profile is only for client-side traffic and that any traffic sent back to the server is sent using HTTP/1.1. Does this still hold true? If so, is anyone...

    "In BIG-IP 11.6.0, F5 introduces HTTP/2 protocol support as defined in RFC7540 for processing client-side HTTP/2 traffic. The support for server-side HTTP/2 traffic processing is introduced in BIG-IP 14.1.0; the webacceleration and OneConnect profiles are not supported in HTTP/2 full proxy mode in this version. In BIG-IP 15.0.0, F5 introduces the support for webacceleration profile in HTTP/2 full proxy mode."

Question related to this. If server-side is set for HTTP/2 but it goes to a server that is HTTP/1,1.1 does it negotiate to the HTTP/1,1.1?

We have a virtual server that would have servers behind it with HTTP/2 but an iRule/Policy is in place for 'exceptions' where it changes the server pool to other servers that are not supporting HTTP/2.

Thanks!!

    Answer my own question after some testing. Yes, it will negotiate and connect to servers that aren't supporting HTTP/2. So I can have a mixed set of servers behind the virtual server some supporting HTTP/2 and others not and it connects successfully.

    I have to note how simple and apparently 'transparent' this is.
