CodgIgniter

<p class="MsoNormal"><span lang="EN-US">CodeIgniter is a PHP based programming framework which implements the model-view-controller paradigm. All HTTP requests have to pass the central index.php file (provided by CI) which initiates the framework controllers to load the views and render a site. So it is not possible to directly call a specific site by entering its URL. To open a specific site the according controller has to be called by passing its name as HTTP-Get-Variable to the central index.php. As a consequence every HTTP request is redirected to one single file and the URLs always contain variables which make them search engine and user unfriendly.</span></p><p>&nbsp;</p>
