So you need access attributes not to context params (which are only
init params). Should be no problem abstracting over those. Give me a
little time.
If you really need in certain cases the servlet-context here is how to
get it
LiftRules.context match {
case context: HTTPServletContext => context.ctx // this is a
ServletContext reference
}
... although I wouldn't recommend adding such dependencies.
