Can i disable SessionState in PageControllerBase

Hi Team,

As of now, I am not using any Sessions in my application so i am planning to disable SessionState in Base controller level to improve the performance. Below is code which i am doing.

[SessionState(System.Web.SessionState.SessionStateBehavior.Disabled)]
public abstract class PageControllerBase<T> : PageController<T>
where T : SitePageData
{

}

So my question here is, If i disable session anything will break in CMS features? Is there any dependency with session across the CMS platform.

Thanks,

Suresh B
