Advanced Controller Routing (based on domain)

[eluser]toopay[/eluser]
With above suggestion, each domain is a single independent application, which use same framework resource (in this case, CI). That mean each application has its own resource. If you need, to share common resource (like core, config, helper, libraries etc) in your each application its look like HMVC with one application folder (with modules) is your solution instead create multiple application. Search on forum or wiki 'HMVC' or 'Modular CI' for that. Then you may just need to set a proper htaccess on every domain/sub domain to redirect it properly to each modules.
