I have created a single page fragment cache but looking at application log it seems like Yii is making two requests. Why does it do that?

Is there any config option to disable this? I use APC extension so it's faster for me to parse those rules again using cached bytecode than to make request to a busy database.

You can use CApcCache for 'cache' component.
