I hope this is the correct section to ask this but does anyone know of a freeware/opensource piece of software that i can use to split my ad traffic? For example i have a 468X60 banner and i want to split it like this: All US traffic go to advertising company A All Euro (Tier 2) traffic go to advertising company B All other traffic go to advertising company C I don't know if this is possible as most ad company's provide a javascript code and not a static image. Please advice?
