 Codeiniter would guess your environment URI to implement pretty URL, if your Codeiniter application is under a sub folder of webroot, you just need to set the web server try file to current directory.
 
+The following example would use `/_projects/codeigniter` as subdirectory path.
+
+### Application BaseUrl
+
+From the orignal Codeigniter config file `application/config/config.php`:
+
+```php
+$config['base_url'] = '';
+$config['index_page'] = 'index.php';
+```
+
+We could set subdirectory path to `base_url` and disable `index_page`:
+
+```php
+$config['base_url'] = '/_projects/codeigniter';
+$config['index_page'] = '';
+```
+
+After setting, you would able to consistently bind URL when you use Url generator:
+
+```php
+$this->load->helper('url');
+echo site_url('controller/action'); 	// `/_projects/codeigniter/controller/action`
+echo base_url("controller/action");	// `/_projects/codeigniter/controller/action`	
+redirect('controller/action');		// Go to `/_projects/codeigniter/controller/action`
+```

 ### Apache Configuration
 
 It's easy to set pretty URL for Codeiniter in Apache where ever the application directory is, add `.htaccess` in the webroot directory:
