What does %H parse?

[remino]

I have a standard NCSA log format, to which every line has two extra fields: the scheme (http or https), and the virtual host name.

So I’m specifying a custom format:

goaccess \
     --date-format "%d/%b/%Y" \
     --time-format "%H:%M:%S" \
     --log-format "%h %^[%d:%t %^] \"%r\" %s %b \"%R\" \"%u\" %H %v” \
     ...

According to the manpage, that should be correct:

       %v     The canonical Server Name of the server serving the request (Virtual Host).
...
       %H     The request protocol.

Now in my generated reports, I see virtual hostnames, but they are formatted like this:

ttp example.com
ttps example.com
ttp example.net
ttps example.net

Am I using %H correctly? If not, can the manpage elaborate what it means by “The request protocol” by citing a few examples?
