  1. As we look at the figure above, when any request arrives at CodeIgniter, it will initially proceed to the index.php page.
  2. After this, Routing will make the decision of letting this request pass to step 3 for Caching or to step 4 for Security check.
  3. If this requested page is in Caching, then Routing may move it to step 3, and hence, the response will return to the user.
  4. If this requested page has no existence in Caching, then Routing will advance it to step 4 for Security check in the structure.
  5. Prior to moving this request to the Application Controller, the Security of the proposed databases are examined.  Once the Security issues are checked, the Application Controller will proceed to load the necessary Libraries, Models, Views, Scripts, Plug-ins, and Helpers, and move it to the View.
  6. The View then will provide the page with some accessible data and move it on to Caching.  This requested page was not continued to cache previously.  But this time it will be ordered to cache in Caching to move this page rapidly for potential requests.
