Sorry for the question but what is Edgecast? Is that the kind of web script?
Edgecast content delivery network
What is a CDN : A content delivery network or content distribution network (CDN) is a system of computers containing copies of data, placed at various points in a network so as to maximize bandwidth for access to the data from clients throughout the network. A client accesses a copy of the data near to the client, as opposed to all clients accessing the same central server, thereby causing a bottleneck near that server. ( wikipedia)
