my web2py is forever "on". when i switch on my Raspberry-Pi, the web2py server is alive and i can access the webpage from another comp in the same network. Btw, thank you so much for your patience and help. :) It seems to work suddenly which i still could not figure out why! :/ just that i'm still stuck at mapping URL, writing arguments and things like that. Is there any site with good complete examples? i couldn't digest the web2py manual without matching examples :(
