How to specify a SEO friendly url like twitter www.twitter.com/<name> using YII framework

I am currently using the Yii framework, and I would like to know if anyone has any clue on how to setup a SEO friendly url like www.twitter.com/ automatically in Yii? I know how to do so this manually in the config/main.php but I would like to be able to dynamically generate it. I have been able to do it in Grails as well. In Yii, what I know of is that you need to开发者_JAVA百科 have another parameter like www.twitter.com/l/, but I do not want that parameter, anyone can share?

Thanks.

Edit the config file main.php with this

'components'=>array(

            .....

            'urlManager'=>array(
            'urlFormat'=>'path',
            'rules'=>array(
                '<controller:\w+>/<id:\d+>'=>'<controller>/view',
                '<controller:\w+>/<action:\w+>/<id:\d+>'=>'<controller>/<action>',
                '<controller:\w+>/<action:\w+>'=>'<controller>/<action>',
            ),
        ),

            ....

I think it is generated when you create a webapp with yiic-tool

Are you not able to achieve what you want by using the URL Manager? If not, can you post an example of what you have currently and what you'd like it to be?
