So you stated that fcl-web uses httpd to provide its functionality, which is incorrect.
No, I stated that httpd
MEANS webserver.... And you can write a webserver, daemon or not, with fcl-web.
httpd is not defined as a protocol. It simply means a webserver implemented as a daemon. Nothing more, nothing less.
You are studying informatics. Don't look stupid. I do not have to watch my words, I tell it like it is. Harsh. and hard if I need to.
Reflect on this.
Apologies accepted.
