I want to start a free internet cafe in a small town in Ecuador. Here is a link to another forum on the topic: http://forums.digitalpoint.com/showthread.php?t=766628 Someone mentioned that I could display ads to the users by creating a transparent proxy server between the client PCs and the net. Does anyone know how to do this? Basically I want to make it so that I can run ads for local companies on the top of every page that the free internet cafe user views.
