At the moment, our WAF implementation does not support HTTP/2 but offers partial compatibility. Incoming HTTP/2 requests will be automatically downgraded to HTTP/1.1 before being forwarded to your server. You server will always see HTTP/1.1 traffic and users will not experience any disruption since the conversion is completely seamless.
We do not support bidirectional HTTP/2 features such as server push, neither do we support request/response multiplexing. Such features are incompatible on a fundamental level with a reverse proxy solution such as the FGX-Web Web Application Firewall. Therefore, we do not have immediate plans for supporting such features currently.
