HTTP/3 requests are incorrectly counted as 'Version 1.1' in HTTP profile statistics, instead of 'Version 3.0,' when HTTP/3 traffic is received on an HTTP/3 virtual server.
Request statistics for the HTTP/3 profile are not incremented for HTTP/3 requests, misleadingly suggesting that HTTP/3 is not being used.
A virtual server is configured with HTTP/3 and QUIC, and HTTP/3 traffic is transmitted.
