configuring HTTP/2 properly

Hi am_gli 

When you say "if MRF is disabled" the serverside is HTTP 1.1 <- this is by design as the configuration is acting in "gateway mode" which means that clientside can serve H/2 to enable the benefits of the protocol while having servers remain on H/1.1

Would you be able to let us know the TMOS version you are using?

Also, do you have a request-logging profile? https://cdn.f5.com/product/bugtracker/ID1101181.html
