abstract class ScreenVar[T] extends NonCleanAnyVar[T]

Keep request-local information around without the nastiness of naming session variables or the type-unsafety of casting the results. RequestVars share their value through the scope of the current HTTP request. They have no value at the beginning of request servicing and their value is discarded at the end of request processing. They are helpful to share values across many snippets.
