Problem summary

• ****************************************************************
  * USERS AFFECTED: Those that use the Redirect directive along  *
  *                 with the '?', query, in the URL.             *
  ****************************************************************
  * PROBLEM DESCRIPTION: When specifying the Redirect directive  *
  *                      any time a query string matches a       *
  *                      Redirect directive, the Location:       *
  *                      header contains no value.               *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  When a redirect is configured to redirect http requests and the
  URL includes a query (?) the redirect would fail.  The request
  was to be re-initiated using the URL in the 'Location' header
  but a null terminator was put at the beginning of the string
  that is being pointed at, so the 'Location' header was blank.
  As a result the client received no data in the browser and
  eventually the connection times out.
  

Problem conclusion

• The string that is being pointed at (the URL) to be included
  in the 'Location' header no longer begins with a null
  terminator.
