multiple CI for different browsers

[eluser]netrox[/eluser]
I decided that it's best to go with multiple apps for different browsers. I do not find "one model fits all devices" workable nor usable enough. I'd rather have the app be optimized for popular devices.

My question is how do I do this? I want to detect a browser being used then redirect an user to an application folder where it's optimized for that browser.

I know that you can manage multiple apps with a single CI but how, exactly? I need to use CI first to detect sessions and browsers then decide on which application the user should be redirected to.
