Hey Juergen,

thanks for this great article! 👍

You can add https://cdn.f5.com/product/bugtracker/ID1196505.html (see https://techdocs.f5.com/kb/en-us/products/big-ip_ltm/releasenotes/related/relnote-supplement-bigip-17-5-1-3.html#A1196505-2) to the list of known issues as well, which makes Full-Stack HTTP/2 almost unusable in many environments. 😒

Greetings,

Sven

F5 needs to work on AWAF with HTTP/2 for 21.x hopefully as  https://my.f5.com/s/article/K000135679 gRPC is also not supported on HTTP/2 but Nginx App Protect WAF that is again the bd process as BIG-IP AWAF supports it and I find that strange.
