Dear Enrico,
Ok, I understand
Yes, basically they are the same, but modharbour CGI provides a set of functions that easy the work very much:
https://github.com/FiveTechSoft/mod_harbour/wiki
Please review the functions and classes.
The wiki may be not completed, so we should scan modharbour sources and see what functions are not documented yet.
modharbour has from "sessions" to automatic cookies management, it provides as hashes the "GET" and "POST" pairs, many things
that really easy the web development work
It has the experience as almost three years working and learning with mod_harbour
