magento - To redirect the page to current instead of logout page -

i working on logout button of magento. when click on logout button going logout page , redirect current page.

in logout page template

<div class="page-head">     <h3><?php echo $this->__("you're logged out") ?></h3> </div> <p><?php echo $this->__('you have been logged out , redirected our homepage in 5 seconds.') ?></p> <script type="text/javascript"> settimeout(function(){ location.href = '<?php echo $this->geturl() ?>'},5000); </script> 

and in customer.xml found

<reference name="root">     <action method="settemplate"><template>page/1column.phtml</template></action> </reference> <reference name="content">     <block type="core/template" name="customer_logout" template="customer/logout.phtml"/> </reference> 

now want redirect page direct current page instead of going logout page. hope understand , me.

have took @ existing magento code handles logout ?

class mage_customer_accountcontroller

/**  * customer logout action  */ public function logoutaction() {     $this->_getsession()->logout()         ->setbeforeauthurl(mage::geturl());      $this->_redirect('*/*/logoutsuccess'); } 

see "setbeforeauthurl()" function ? try play inject current url can retrieve : mage::helper('core/url')->getcurrenturl();
