title: Is there a global REQUEST handler for CodeIgniter or at least PHP like in Global.asax on ASP.NET?
body: <p>In ASP.NET I have the <code>Application_AcquireRequestState</code> method in <code>global.asax</code> so that I can handle all requests that hit my application, so then I can do some things like take care of cookies or URL segments or anything I want before execution of the controller code itself</p>
  
  <p>Is there anything like that in PHP or in CI specially?</p>
