[18:28:08] <Reedy>	 Anyone about familiar with the HTTP/2 spec?
[18:28:36] <Reedy>	 Is GET foobar HTTP/2.0 valid? It doesn't seem to be, and the only mention of 2.0 like that I can find is in https://tools.ietf.org/html/rfc7540#section-3.5
[18:28:48] <Reedy>	 That is, the connection preface starts with the string "PRI * HTTP/2.0\r\n\r\nSM\r\n\r\n"
[18:30:58] <Reedy>	 Except IIS seems to pass GET * HTTP/2.0
[18:30:59] <Reedy>	 https://docs.microsoft.com/en-us/iis/get-started/whats-new-in-iis-10/http2-on-iis
[18:32:05] <Reedy>	 Which could just be an ooolld doc
[19:40:46] <Reedy>	 Looks like in responses, it's just HTTP/2 200 etc
[19:40:46] <Reedy>	 $ curl -I "https://en.wikipedia.org/w/api.php"
[19:40:46] <Reedy>	 HTTP/2 200 
[19:50:45] <Platonides>	 Reedy: seems that the first connectiong would need to be GET /foobar HTTP/1.1, with an Upgrade: h2c header
