Question : SessionState

I've been having a sessionstate timeout at DiscountASP and they recommended that I use SQL Server to set my session state.

The example they sent is attached...
What are the "good-bad" sides of this and do I need to do anything else except dump this in my web.config?

Code Snippet:

         
             < sessionState
  mode="SQLServer"
  allowCustomSqlDatabase = "true"
  sqlConnectionString="data Source=;database=;user id=;password="
  cookieless="false"
  timeout="15"
/>
