+<h2>Remapping Function Calls</h2>

+<p>As noted above, the second segment of the URI typically determines which function in the controller gets called.
+Code Igniter permits you to override this behavior through the use of the <kbd>_remap()</kbd> function:</p>

+<code>function _remap()<br />
+{<br />
+ // Some code here...<br />

+<p class="important"><strong>Important:</strong> If your controller contains a function named <kbd>_remap()</kbd>, it will <strong>always</strong>
+get called regardless of what your URI contains. It overrides the normal behavior in which the URI determines which function is called,
+allowing you to define your own function routing rules.</p>

+<p>The overriden function call (typically the second segment of the URI) will be passed as a parameter the <kbd>_remap()</kbd> function:</p>
