iRule sideband using HTTP/2

All examples I have seen with iRules using 'connect' to generate a sideband connection use HTTP/1.0 or HTTP/1.1 I am wondering if anyone has examples of, or knows how iRule sideband connections can ...

    You would indeed use a helper VIP here to do a sideband call. The trick is, the HTTP2 profiles require client and server SSL and client and server HTTP2 profiles. But you can get around that.

    • Configure your helper VIP accordingly
      • HTTP profile
      • Client SSL profile with Renegotiation disabled
      • Server SSL profile with Regenotiation disabled
      • HTTP2 client profile (under Acceleration)
      • HTTP2 server profile
      • VLAN: listening on none
      • Pool to resource
    • Add the following iRule to the help VIP:
        SSL::disable clientside

    So then traffic should come to the VIP unencrypted, the iRule will disable clientside SSL and HTTP2, then encrypt with HTTP2 to the server.
