Now I think I can answer myself, after a few tests on a local environment,
maybe this can be useful for someone in the future having the same doubts
(including me).
_front__tls is a mode tcp proxy, so the number of active sessions, listed by
show sess, will be the same the number of connections to that frontend.
_front_http and _front_https are mode http proxies, so the number of active
sessions, listed by show sess, will be the number of running http requests. As
soon as the http request finishes, the session disappear from the list, event
though the client is still connected to the frontend - global ConnCurrs counts
this.
The difference between global ConnCurrs (show info) or scur (show stat) and the
list above (show sess) is apparently the active connections, counting in show
info and show stat, without a running http request or a http tunnel (eg
websocket), so without counting in show sess. If my assumption is correct, "
4. scur [LFBS]: current sessions" from the management guide could be clarified
on how it works on mode http frontends.
