Problem with passing parameters in URL

HI all,

I have a problem with passing parameters in the URL.

here is my urlmanager configuration




			'showScriptName' => false,


                           	'user/<action:(login|logout|register)>' => 'user/<action>',




and I am trying to generate a link like this

but when I use

CHtml::link('link to category', array('/', 'cat'=>'category_name', 'subcat'=>'subcategory_name'))

in generates this link

I don’t want parameters names in the URL. What should I do?

Yii version: 1.1.8.r3324
