  37.     control what information about the server will be presented
  38.     in server-generated documents such as error messages. The

  44.     directives are used by the server to determine how to construct
  45.     self-referential URLs. For example, when a client requests a
  46.     directory, but does not include the trailing slash in the
  47.     directory name, Apache must redirect the client to the full
  48.     name including the trailing slash so that the client will
  49.     correctly resolve relative references in the document.</p>
