multiple arduino based web server, single web page

I have a arduino board connected to multiple sensors and actuators and ethernet controller enc28j60 . I can control this arduino controller with a single web page showing all sensor values and control actuators. I find numerous examples of such cases using UIPethernet library and a web page hosted on PC , fetching values from arduino with the help of enc28j60 ethernet controller. Now i require multiple such arduinos along with multiple ethernet controllers all connected to switch and PC connected to switch . This PC is dedicated to control all these arduinos over internet requesting data from multiple arduinos and ethernet controller. Can somebody write in this regard how to parse sensor/actuator data effectively from each arduino to PC and PC web page refreshing itself every 5 seconds or so.
