问题 I'm creating a SaaS web app in codeigniter and i'm trying to determine how to route to a specific controller based on whether a subdomain exists or not.

问题 I am using codeigniter framework. And i am searching for a best practice to multi-thread using MVC framework of codeigniter.

If you want the value of function foo() to be passed to function bar()

问题 I’ve looked in the forums (both here and on CodeIgniter.com) but haven’t found any answers that help. I have a CI 2.0.2 app that I developed locally in MAMP. It works perfectly. I copied the entire CI install up to our QA server, and am getting 403 Forbidden errors on every single page (even the default.)
