How can i update asset path in Yii1?

Question

Currently asset render with path

http://localhost:8080/assets/b9cee958/pager.css

but, I want to render asset using the controller action, e.g.

http://localhost:8080/manager/renderAsset?id=/b9cee958/pager.css

Where in ManagerController, i have action RenderAsset where actually want to give the base path.

How can i do that ??
