Using Arduino as Intermediate between a PC and an iPad

Hi,

Ok I have a server which has plenty of contents stored inside and I need iPad to send a command to arduino which has been programmed to take out specific data that I'm asking from my iPad. My iPad will communicate and send command to arduino via wifi. But arduino task is to take the data from a server(which is my PC) and present it to my iPad. I don't know how will arduino be connected to PC as the wifi will be use to send data to iPad. Can the wifi work both ways? Can the project be done?

BTW Thanks Geoff!
