Convert w5100 code to yun shield

hi!
i have make small home automation mega , w5100 ethernet shield, it's going slow project go forward.

i want use yun shield able upload sketch wireless , host webpage on usb stick.

the wifi working upload sketch , can access files usb wireless, cannot make code running. there way keep html page , code same thing in yun in w5100?

please help!

my code
