Re: Making HTTP2 requests

Ah, no I was just looking at the version and I thought 8.01 did but I guess
it's not listed in features.

> curl -V
curl 8.0.1 (Windows) libcurl/8.0.1 Schannel WinIDN
Release-Date: 2023-03-20
Protocols: dict file ftp ftps http https imap imaps pop3 pop3s smtp smtps
telnet tftp
Features: AsynchDNS HSTS HTTPS-proxy IDN IPv6 Kerberos Largefile NTLM
SPNEGO SSL SSPI threadsafe Unicode UnixSockets

It's odd that it accepts the http2 options if it doesn't support it.
