docs: Looks up a configuration variable in the "request" scope.
  <p> The lookup of configuration variables is performed as if each scope
  had its own name space, that is, the same configuration variable name
  in one scope does not replace one stored in a different scope.
  
  @param request Request object in which the configuration variable is to
  be looked up
  @param name    Configuration variable name
  @return The <tt>java.lang.Object</tt> associated with the configuration
  variable, or null if it is not defined.
