Like many crazy ideas, this one originates in a longstanding wish of mine: To be able, independently for each application running on my system, to determine whether that application will channel its internet traffic through a proxy server or not. For some inexplicable reason, very few apps out there provide their own, "local" settings. Most rely on the global OS settings (under System Preferences > Networking). OmniWeb and DevonAgent, for instance, are two tools that lack this capability, and I find that to be a glaring omission. Numerous users share this view on the forums. So, here's an idea: Would it be possible to create a "wrapper" application which would "hijack" the internet traffic of a given application and route it via a proxy server, overriding the global OS setting? Would this be feasible via Cocoa APIs or would it require some dark programming magic? Thank you.
