Session[Constant] vs Session["String Literal"] Performance

I'm retrieving user-specific data like ViewData["CartItems"] = Session["CartItems"]; with a string literal for keys on every request. Should I be using constants for this?

If yes, how should I go about implementing frequently used string literals and will it significantly affect performance on a high-traffic site?
